Notes 4

Question 1

Volume expansion

Answer 1

When an object changes temp every dimension including volume changes

Question 2

Factors that affect how fast heat is transferred through an object

Answer 2

Density
Type of material

Question 3

Thickness of material for heat transfer

Answer 3

(Heat transfer gets smaller if thickness is bigger, heat transfer gets bigger if thickness is smaller)

The rate of heat transfer is inversely proportional to the thickness of material. The thicker the material the slower the heat transfer.
