Question

When the temperature of 0.25 kg of ice cream is increased from -10’C to -2’C, the heat supplied is 3000 J. Find the specific heat capacity of the ice cream.

Answer 1

To find the specific heat capacity of the ice cream, the formula Q = mcΔT is used, where Q is the heat supplied, m is the mass of the ice cream, c is the specific heat capacity, and ΔT is the change in temperature. Plugging in the given values and solving for c, the specific heat capacity of the ice cream is found to be 150 J/(kg·°C).

Step-by-step explanation:

To find the specific heat capacity of the ice cream, we can use the formula Q = mcΔT, where Q is the heat supplied, m is the mass of the ice cream, c is the specific heat capacity, and ΔT is the change in temperature.

Given that the mass of the ice cream is 0.25 kg, the change in temperature is -2°C - (-10°C) = 8°C, and the heat supplied is 3000 J, we can plug these values into the formula and solve for c:

3000 J = (0.25 kg) * c * 8°C

c = 3000 J / (0.25 kg * 8°C) = 150 J/(kg·°C).
