Our bodies experience temperature as hot, cold, or in between. However, scientists think about temperature as the ______ of _______.

• mass; object as a whole
• movement; object as a whole
• movement; object's particles
• mass; object's particles

The average kinetic energy of the individual particles in a given quantity of matter is called its ___________.

• Temperature
• Mass
• Momentum
• Elastic Energy

Microwaving a mug of hot chocolate will make the molecules of the hot chocolate move ________, thus giving it _______ KE.

• Faster; more
• Slower; more
• Faster; less
• Slower; less

If a liquid is hot, its molecules move more quickly than when it is cold. This also causes them to take up more space since they bounce off one another and off the container with more energy.

• True
• False
