Question

The temperature of a 5.0 kg block increases by 3 degrees C when 2,000 J of thermal energy are added to the block. What is the specific heat of the block? _____________

Answer 1

133.33J/kg°C

Step-by-step explanation:

Given parameters:

Mass = 5kg

Temperature change = 3°C

Thermal energy = 2000J

Unknown:

Specific heat of the block = ?

Solution:

To find the specific heat capacity, use the formula below;

H = mCФ

where H is amount of heat

m is the mass

C is the specific heat capacity

Ф is the temperature change

Input the parameters and solve;

2000 = 5 x C x 3

C =
`(2000)/(15)`

C = 133.33J/kg°C
