Why do water droplets form on a lid when boiling water?
The lid is cooler than the steam (water vapor) produced by boiling the water. When the water vapor contacts that cooler surface, it condenses into liquid water.
Why is it that when a football is blown until it is hard on a hot summer day and then in the evening the football feels softer?
When air gets warm it expands causing the football to overinflate. When the air gets cooler the air compacts causing the football to feel softer.
When water evaporates the air near the water's surface becomes cooler.?
merp. because the temperatures particles are changing because they are changing state and at the surface of the water the particles are changing into a gas so its temperature is decrease as the energy decreases also
What is the energy transferred from a hotter object to a cooler one is referred to as?
This is the zeroth law of thermodynamics: objects at different temperatures will form a thermal equilibrium. The first law of thermodynamics says that energy can not be created or destroyed but can only change form. So the cooler object has to get hotter not the other way around.
When you have a cooler filled with ice and bottles of Gatorade why doesn't the Gatorade freeze?
because the freezing point of Gatorade is lower than the tepurture of the cooler
When warm air near the surface of the Earth rises cooler air tends to rush in to take its place This sort of heat transfer is known as?
convection

Why might a major volcanic eruption lead to cooler temperature over a large area around the volcano?
Blocking of solar radiation from ash in the atmosphere causing less radiation to reach surface cooler temperatures. *I <3 cupcakes!*:)
The smoke from a bonfire rises upwards?
It is hot, and less dense than the air it displaces. It floats of the cooler, denser air.
The smoke from a bonfire rises upwards why?
It is hot, and less dense than the air it displaces. It floats of the cooler, denser air.
When water is evaporated from a surface does the surface get cooler or hotter?
The surface become colder.
What is heat a transfer of?
Heat transfer is the transition of thermal energy from a heated item to a cooler item.
When a warmer object touches a cooler object what does heat move by?
if you mean to what way it transfer, always the heat is going to move to the cooler object. The means of heat transfer is conduction.
What are the cooler areas on the suns surface?
sunspots
What technology is associated with a portable cooler?

What is a dark area on the surface of the sun that is cooler than the surrounding area?
Sunspots are dark areas on the sun's surface that are cooler than the surrounding area.
