Answer:
A) 84 calories
Explanation:
Specific Heat Capacity is the energy, transferred as heat, that is required to raise the temperature of one gram of a substance by one degree Celsius.
Quantity of heat = mcΔt; Where m is the mass in kilograms, c is the specific heat capacity and Δt is the change in temperature.
Mass = 10 g, specific heat capacity = 0.21 cal g°C, and Δt = 10 °C
Therefore;
Heat = 10 × 0.21 cal g°C × 40 °C
= 84 calories
