d)

Mrs. Shade is heating a pot of water on the stove. How is the motion of the water particles different after the average kinetic energy or temperature of the water increases?
a) The particles would, on average, speed up.
b) The particles would, on average, slow down.
c)
d)

Zoe notices that the air in her science classroom is much warmer than the air in her math classroom. Which statement describes how the air particles are different in her colder math classroom?
a) They have less average kinetic energy.
b) They have more average kinetic energy.
c)
d)

What things does thermal energy depend on?
a) temperature (average kinetic energy of molecules)
b) the number or amount of particles (mass)
c) how the particle are arranged
d) all of these

the words hot, warm, cool, and cold are used to describe this; the average kinetic energy of the molecules in a material determines how hot or cold something is
a) temperature
b) thermal energy
c) heat
d)

a) True
b) False
c)
d)

The particles that make up substances move. Each of these particles adds to the total amount of kinetic energy the substance has.
a) True
b) False
c)
d)

Temperature is measured using one of three scales: Celsius, Fahrenheit, and Kelvin.
a) True
b) False
c)
d)

Which pumpkin would have the most thermal energy?
a) A LARGE pumpkin because it contains the most particles or has the greatest mass.
b) A SMALL pumpkin because it contains the least particles or has the smallest mass.
c) They would have the same thermal energy.
d)
