Answer: 16700 Joules
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed = ?
m = mass of sand = 2 kg
c = heat capacity =
Initial temperature = =
Final temperature= =
Change in temperature ,
Putting in the values, we get:
16700 J of energy must be added to a 2-kilogram pile of it to increase its temperature from 40°C to 50°C
