Molecular Speed
Equilibrium
Which item is hotter?
100

The molecules of an object speed up.

What happens when an object gets warmer?

100

I have a sample at 6 degrees Celsius and a cup of water at 6 degrees Celsius and put them together. 

What is an example of equilibrium?

200

The temperature of an object gets colder.

What happens when the molecules of an object slow down?

200

I have two equal-sized cups of water at 8 and 10 degrees Celsius and put them in contact.

What two cups have an equilibrium temperature of 9 degrees Celsius?

300

An object's molecules speed up after coming into contact with a warmer object.

What happens to the molecules of an object after it touches a warmer object?

400

I have two samples at 6 degrees Celsius, but the larger one has more molecules and more total kinetic energy.

What is an example of a larger sample having more thermal energy than a smaller sample?
