Question 1 • TX-Chemistry B-CR

Which statement best describes why specific heat capacity is often more useful than heat capacity for scientists when comparing two materials?

Answer
A
Specific heat capacity is an intensive property and does not depend on sample size.
B
Specific heat capacity is an extensive property and does not depend on sample size.
C
Specific heat capacity is an intensive property and depends on the sample size.
D
Specific heat capacity is an extensive property and depends on the sample size.

Explanation

Specific heat capacity is the heat needed to raise the temperature of one unit of mass by one degree. Because it is measured per unit mass, it does not change when the sample size changes, making it an intensive property. Heat capacity, by contrast, depends on the total amount of material.
