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

Answer:

133.33J/kg°C

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  = $\frac{2000}{15}$

         C = 133.33J/kg°C
