Question 2

Question 1
When does the addition of heat result in a rapid temperature rise?
When the material has a low latent heat of vaporization.
When the material has a high latent heat of vaporization.
When the material has a low specific heat.
When the material has a high specific heat.

Question 2
A student designed an experiment to investigate how emergency thermal blankets are used to
keep a person warm in a cold environment. The student heated water on a hot plate until it
reached a temperature of 100 0C. Equal amounts of the water were quickly transferred to
identical containers. One of the containers was wrapped with a layer of aluminum foil and the
other with clear plastic wrap. A thermometer was inserted into each container so that they
touched only the water. After one hour of observation, the temperature of the water in the
aluminum wrapped container was higher than the plastic wrapped container.

Based on the specific heat data, is the observation consistent with predicted results? Why or why
not?
Yes, it is consistent because the plastic wrapped container should have a
lower temperature after one hour because it would transfer heat slower.
No, it is not consistent because the aluminum wrapped container should
have a lower temperature after one hour because it would transfer heat
faster.
No, it is not consistent because the plastic wrapped container should have a
higher temperature after one hour because it would transfer heat faster.
Yes, it is consistent because the aluminum wrapped container should have a
higher temperature after one hour because it would transfer heat slower.
