7. Bob and Mike are discussing why volume increases when a substance is heated. Bob says, “The warmer particles move farther
apart and the particles themselves are expanding (getting larger).” Mike disagrees and says, “The particles are moving farther
apart but the particles are not expanding.” (2 pts)
a. Who do you agree with? ___________
b. In your own words, explain what change in the particles causes the volume to increase when a substance is heated.

2) The temperature of a plastic cup is 70*C. It is filled with 40*C water. Which of the following describes how thermal
energy is transferred?
a) Thermal energy is transferred form the water to the cup until they are both 45*C.
b) Thermal energy is transferred from the cup to the water until the y are both 45*C.
c) Thermal energy is transferred from the cup to the water until the cup is at 60*C and the water is at 50*C.
d) No thermal energy is transferred between the cup and the water. The cup will remain 70*C and the water will
remain 40*C.
3) A student places a warm can of soda into a bucket filled with cold water. Which explains the energy transfer between
the water and the can of soda?
a) Thermal energy is transferred from the can of soda to the water so the can of soda cooler and the water stays
the same temperature.
b) Thermal energy is transferred from the can of soda to the water so the can of soda gets cooler and the water
gets warmer.
c) Coldness is transferred from the water to the can of soda so the can of soda gets cooler and the water stays the
same temperature.
d) Coldness is transferred from the water to the can of soda so the can of soda gets cooler and the ice water gets
warmer.
