Why do cups with cold drinks sweat

Double - paned windows are sealed to maximize insulation. If that seal breaks, cracks, or otherwise fails, moisture enters between the panes. Depending on the humidity and temperature outside, it may fog, pool, or collect at the bottom, or it may show up as condensation. Condensation and mould growth While water vapour itself does not cause any health problems, damp conditions and high humidity often lead to mould growth. In large quantities, mould spores can be really bad for your health.

Interior window condensation is caused by excessive moisture in the house, and it often occurs in the winter when the warm air inside the house condenses on the cold windows. Condensation between window panes occurs when the seal between the panes is broken or when the desiccant inside the windows is saturated.

Fixing Condensation on Internal Glazed Faces When cooking, ensure that you cover all pots or pans with a lid. Avoid drying any wet washing inside when possible. When showering, close doors and open a window or use an extractor fan to remove moisture-rich air. Water cannot pass through what we consider to be conventional glassware. However, there are special porous glass systems known as semi-permeable membranes which do allow for the transport of water molecules as well as other molecular species.

The best soda-lime glass. The best plastic tumbler. Dew is the result of water changing from a vapor to a liquid. This forces water vapor in the air around cooling objects to condense. When condensation happens, small water droplets form — dew.

The temperature at which dew forms is called the dew point. Simply put a sock over the bottom of the bottle. The sock will absorb the " sweat " and will also help keep your drink cold longer. During summer season, water vapor presented in the atmosphere is more due to high evaporation rating.

This evaporation rating increases the content of water vapor. The water vapor will form a layer on the surface of the can. This amount of water that can exist as a gas is measured as a pressure. Sweating has a totally different meaning.

Thank you, people at Wonderopolis, for such a great source of information! Wonderopolis Mar 1, Benjamin Nov 1, I learned that Mentos can make Coke fiz up and make a waterfall. I would like to know more about how the Mentos make the Coke fiz. I thought it was interesting that the Mentos is a type of candy, and you can't just put a Kit-Kat in it.

I want to do this at home. Wonderopolis Nov 1, Olivia May 6, When you put Mentos in a soda bottle, it will have a little explosion. When you put 6 Mentos in the cart and the coke moves the cart, the explosion some people call it when the drinks sweat. Wonderopolis May 6, Kylie May 2, Wonderopolis May 2, Thanks Kylie, we sure will!

We hope you'll Wonder with us! Kylie May 1, Wow, that is really cool, that is a lot of mentos and soda, that would be a lot of money :. Wonderopolis May 1, Brianna May 1, Hey I think you guys have an awesome website thank you for what you did to make this website happen.

Eduardo May 1, Dylan May 1, Liles' Class May 1, Joey - I wish there was a better video to match the topic please, because it didn't seem to match the topic. Devante - I have put Mentos in Coke before and it exploded. Kadryn - I like lemonade. Tommie - Robbers? Cooper - A person crying for help and someone helping him.

I liked the experiments they did and that guy was sitting in a small bicycle with the cokes behind him. Wonderopolis Apr 30, Oops, I meant what would be cooler is to make a wonder about special pie. Oh thanks!!! You should make a wonder about pie. Great one unicorn pie !!! H Apr 30, Dear Wonderopolis, I liked the video.

It was funny and last time I went to my friend and I got some soda and some mint and we put it inside the soda and we shook it and it busted up. I think tomorrow's wonder will be about fire. H's student. H's class Apr 30, Wonderopolis that was a funny video. I think that tomorrow's wonder is about Fire Fighters. If there is going to the moon there going to need more Mento and Coke Cola to get there and they'll need helmets. I really like the music it was COOL!

I hope you do a video with that kind of music again. Selea from Ms. H's class. Coleman's Class Apr 30, My dof licks it off. Shaviyana " What is the emergency number? VanDusen's Class Apr 30, Thoughts, Connections, and Questions: Michael- A while ago, I did a coke and mentos challenge with a smaller bottle.

Bryan- Why does it have to be so hot outside every day? Erica- At summer camp we did the coke and mentos experiment and it exploded everywhere. Aaliyah- When I go to the pool, my grandma's water bottle has condensation on it. David- I thought when you put mentos in your drink it comes out like foam. Predictions: Michael- How was the Red Cross formed?

Destiny- How fast do firefighters get to a fire? Bryan- Who made the Superman movie? Erica- How do you get to safety during an emergency?

Stephanie- Why do we cry? Sierra- How do firefighters do their job? David- Why do people follow an ambulance? Josh- What is the cause for kidnapping? Cassie- Where does kidnapping happen most often? Trevon- What forms tears? Hannah Apr 30, Very interesting, I'll have to tell my science-y brother! I think tomorrow's wonder is going to be about why we grow up so fast!! I think tomorrow's wonder is going to be about why we cry and why we grow up so very fast!

Either one of them please!!!! Thanks a lot wonderopolis You have helped me alot thanks again!!!! PC 1st Graders Apr 30, The video of the soda rocket car was awesome!

We'd love to go for a ride on one. Your wonder made us think about lots of different kinds of experiments. We started a book about the science experiments we have done or want to do. Some of them are about plants growing, water freezing, breaking boards, ice cream melting, playing soccer in the air, and even how to make our own soda jetpack! Apr 30, WE thought the video was awesome.

I have seen the water droplets on our car in the morning. The dew on the grass in the morning is the same process-condensation. I wonder how close to the moon they could get? Froggy 1 Apr 30, Hi Wonderopolis, Some people in our class did not know that mentos could explode with diet soda! We didn't know that it had that much power to push a bicycle with a person in it. We liked the video! That was very funny!

How can the soda explode with mentos? Do you think it could be made into a rocket? Why does soda explode when you shake it? We predict tomorrows wonder will be about fire, a bad guy, a baby screaming, somebody screaming because a team won the superbowl, a bear or lion eating someone, falling off something really steep. Miss Marsico's Class Apr 30, Comments: - Jayna- "I learned mentos and coke can move a vehicle ft! Wonder Friend F Apr 30, Bayko's class Apr 30, Thank you for sharing your awesome prediction, Ms.

A condensation chemistry definition is the process of a substance changing from a gaseous to a liquid state. This process is caused by a change in mostly temperature, but also pressure. Also recall how the molecules acted in both the gaseous and liquid states. In a gas, particles have a high kinetic energy.

In a liquid, they have less kinetic energy. A gas has to lose energy to become a liquid. Water beads have appeared on the glass, and, from the definition, this means that water vapor has condensed into liquid on the glass surface. This water vapor is always present in the air, even on clear days. Grasping the water cycle at the point of condensation may help in recognizing how water forms on a cold glass.

In the water cycle, water vapor pushed into the cooler upper atmosphere slows the evaporation rate down to less than the rate of condensation. Condensation occurs at a quicker rate, and the gaseous water molecules condense around tiny airborne particles of dust, salt and smoke to form tiny droplets that can grow by collecting more liquid water molecules. Similar to the cooler upper atmosphere, as the glass in our example from the beginning becomes cold from the ice in the drink, it reaches a temperature where condensation happens at a higher rate than evaporation.

Even on a hot day, and even though hot air can hold more water vapor than cold air, there is an upper limit to how much water vapor air can hold. The movement of particles can explain this increase in condensation rate. When the hot air comes in contact with the cold glass, heat is transferred from the hot air to the cold glass.
