The vapor rises from a cold cup in hot air because the warm air around the cup heats the liquid inside, causing it to evaporate and turn into vapor. The warmer air has a higher capacity to hold moisture, so the vapor rises due to the difference in temperature and creates a visible stream as it condenses.

Why does vapor rise from a cold cup on a hot day?
Vapor rises from a cold cup on a hot day because the cold surface of the cup cools the air immediately above it, causing the water vapor in the air to condense into tiny droplets. These droplets form a mist or fog that appears to rise from the cup as warm air from the surroundings moves in to replace the cooled air.
Why do water droplets form on the inner wall of a covered cup of hot water?
Water droplets form on the inner wall of a covered cup of hot water because the air inside the cup becomes saturated with water vapor from the evaporating hot water. When the air cools against the cooler walls of the cup, it cannot hold as much water vapor, causing the excess moisture to condense and form droplets.
How do you keep a cup cold?
You can keep a cup cold by using a double-walled insulated cup, adding ice cubes, or placing the cup in the refrigerator or a cooler. Additionally, using a coaster or a sleeve can help insulate the cup and keep it cold longer.
What happens to water in a cup when left in the sun?
When left in the sun, the water in a cup will gradually heat up and may reach a higher temperature than its surroundings. Some of the water will evaporate, turning into water vapor and escaping into the air.
How does condensation on a cup occur and what factors contribute to its formation?
Condensation on a cup occurs when warm, moist air comes into contact with the cooler surface of the cup, causing the air to release its moisture in the form of water droplets. Factors that contribute to condensation include the temperature difference between the air and the cup, the humidity level in the air, and the material of the cup.
Why does vapor rise from a cold cup on a hot day?
Vapor rises from a cold cup on a hot day because the cold surface of the cup cools the air immediately above it, causing the water vapor in the air to condense into tiny droplets. These droplets form a mist or fog that appears to rise from the cup as warm air from the surroundings moves in to replace the cooled air.
Where did the water in the outer cup come from?
The water vapor in the air. Since the cup is so cold from the ice inside, the vapor in the air when it hits the cup it causes it to make the water on the outsaide of the cup. You'd think it came from the inside, but it doesn't.
Where did the water droplets come from On the cup of ice?
That's condensation—the water vapor in the air around the cup condenses on its surface because it's cold. So it comes from the air around the cup.
When I pour cold lemonade in a plastic cup why is there water outside my cup and where did that water come from?
The cold lemonade cool the temperature of the plastic cup including the outer side of it. Thereby lowering the amount of water the air can contain, resulting in water condensating - attaching to the cup.
What fact or measurement would allow you to predict how high the pressure of water vapor inside the cup will rise?
Measuring the temperature of the water in the cup would allow you to predict how high the pressure of water vapor inside the cup will rise, as the pressure of water vapor is directly proportional to the temperature of the water.
Can you give me a sentence with the word vapor?
The vapor rising from the hot cup of tea was visible in the cool morning air.
Why there are no water droplets outside of a warm cup?
Condensation can only occur on a glass that is cold. The reason why condensation forms is because water vapor in the air (a gas) cools and turns into liquid water when it comes into contact with a cold surface.
What is the difference between open cup and closed cup flash point?
The fuel sample in the open cup is exposed to air,thereby decreasing it's vapor pressure when compared to the same in a closed cup.
Why does ice form on the outside of a beaker containing dry ice?
The air around the beaker is cooled by the intense cold of the dry ice, causing water vapor in the air to condense and freeze on the surface of the beaker. This results in the formation of ice on the outside of the beaker.
Why doesn't a cup of coffee sweat?
'Sweat' on a cup is caused by condensation of moisture on the air on a cold surface. Cold causes the air to lose its ability to hold as much moisture. Since coffee is hot, it is increasing the ability of the air to hold moisture. You will only get the sweat on a cold drink. And the air in your house in winter is very dry, so there is not much to condense on cold items.
When a cup is put in the freezer and then taken out how does moisture form?
It is called condensation. It is when the Coldness around the cup slows down the moisture in the air ( because moisture is fast in molecular speed) and turns it back into a liquid. The moisture in the air is warm and cooled and slowed down
Where does the water on a cold drink come from?
Moisture in the air around the glass, cup, etc.
