What is the specific heat capacity for a 5 g sample of metal that absorbs
100 Joules of heat energy when its temperature changes from 10 degrees
C to 40 degrees C?*
A) 15, 000 J/gC
B) 2 J/go
C)0.67 J/gC
D) 0.50 J/go

The specific heat capacity is 0.67

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

The amount of heat that a body receives or transmits is determined by the following expression:

Q = c * m * ΔT

Where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

This expression indicates that between heat and temperature there is a direct proportional relationship.

In this case:

Replacing:

100 J= c*5 g* 30°C

Solving:

c= 0.67

The specific heat capacity is 0.67
