What effect does the obsence of heat have on air molecules?
When heat touches air molecules they speed up but when cold air touches molecules they slow down.
Do air molecules move fast in hot weather or slow?
Air molecules move faster in hot weather and slower in cold weather.
How do you change a gas into a solid?
you would have to put it in a really cold place where the molecules can slow down and go from gas to liquid to solid.
Why does hot water hold more dissolved solids than cold water?
the molecules are moving around faster and are more spread out, therefore leaving room to dissolve more solutes. Cold water molecules are moving slow and are close together.
Why does gasoline shrink in cold weather?
Most materials shrink in cold weather and expand in hot weather because the molecules slow down when cold The most notable exception, of course, is water, which expands as it freezes.
What effect does the obsence of heat have on air molecules?
When heat touches air molecules they speed up but when cold air touches molecules they slow down.
What is circulation in a kettle?
(I Guess) Hot molecules moving up while cold molecules move slow (down) until excited by the hottness.
Do air molecules move fast in hot weather or slow?
Air molecules move faster in hot weather and slower in cold weather.
Why does cool water move slow?
Cool water moves slow because the molecules are moving slow. In hot water, molecules are moving fast, thus, hot water seems to move faster than cold water at times.
When you are measuring temperature you are measuring the?
How fast molecules are moving. If they are moving fast its hot, but if they are moving slow it is cold
What makes hot air turn to cold air?
Heat is defined by how fast molecules are moving. Fast moving molecules will have a higher temperature than slow moving molecules. The kinetic energy of the hot air is transferred to the cold air, which means the cold air becomes a little warmer, and the hot air becomes cooler.
Why does heat flow from a hot to cold body?
Heat flows from hot to cold because when hot and cold bodies contact with each other (thermal contact), the fast moving molecules of the hot body collide with slow moving molecules of the cold body; therefore the molecules of hot body become slower and body becomes cool, and the molecules of other body (cold) becomes faster and the cold body becomes hot. Notice: when molecules of a body moves faster it's kinetic energy increase therefore temperature increases and it becomes hot.

Why is Quito Ecuador cold?
It's in the mountains, causing the altitude to mess with the air molecules, making them slow down.
Why does hot water hold more dissolved solids than cold water?
the molecules are moving around faster and are more spread out, therefore leaving room to dissolve more solutes. Cold water molecules are moving slow and are close together.
