18.1 Heat and Matter: Heat on the Move
Exercise 72
A. Below are descriptions of things people do to get warm.
On the first line below each description, write whether
heat moved through a solid,
liquid, or gas to reach the
person. Then, on the second line, write the word
conduction, convection, or radiation to describe how the
heat was passed along.
