If 150 kcal of heat raises the temperature of 2.0 kg of a material by 400°F,what is the specific heat capacity of the material?

Question

Quizplus · Accepted Answer

Firstly, we need to convert the temperature from Fahrenheit to Celsius by subtracting 32 and dividing by 1.8:

400°F = (400-32)/1.8 = 204.4°C

Then we use the formula:

Q = m * c * ΔT

where Q is the heat energy transferred, m is the mass of the material, c is the specific heat capacity of the material, and ΔT is the change in temperature.

Plugging in the given values and converting to the appropriate units:

150 kcal = 2.0 kg * c * 204.4°C

c = 0.34 kcal/kg*C

Therefore, the specific heat capacity of the material is 0.34 kcal/kg*C, which corresponds to answer choice C.
