Intro to Physics: Chapter 7.3 & 7.4 – What is Heat & Heat Transfer
Before reading: Examine the statements below and indicate whether you agree or disagree with each one.
Statement
Agree Disagree
1.) The amount of thermal energy an object has depends on its temperature & the
amount of matter in it.
2.) Heat flows naturally from a colder object to a warmer one.
3.) The metric unit for measuring heat is the degree.
4.) If an object’s specific heat is low, its temperature will change relatively quickly, &
if an object’s specific heat is high, its temperature will change relatively slowly.
5.) In general, materials made up of heavy atoms or molecules have high specific heat
compared with materials made up of lighter ones.
6.) Conduction only occurs between two materials at different temperatures & when
they are touching each other.
7.) Thermal equinox occurs when two bodies have the same temperature & no heat
flows.
8.) Conduction happens only if there are particles available to collide with one
another, so it cannot occur in the vacuum of space.
9.) Convection is the transfer of heat through the motion of fluids such as air & water.
10.) Thermal radiation cannot travel through the vacuum of space.
After reading: Reexamine your responses to the statements. Rewrite each statement below, correcting
those that are incorrect. Write the page number where the correct information can be found in the text.
