Answer:
2.0 J/g°C
Explanation:
We are given;
- Quantity of heat as 10.0 kJ
- Mass of the substance as 100 g
- Temperature change is 50°C
We are required to calculate the specific heat capacity of the substance;
- We need to know that the quantity of heat gained by a substance is given by;
Quantity of heat = Mass × specific heat × change in temperature
That is;
Q = mcΔT
Rearranging the formula;
c = Q ÷ mΔT
Therefore;
c = 10000 J ÷ (100.0 g × 50°C)
= 2.0 J/g°C
Thus, the specific heat of the substance is 2.0 J/g°C
