Question

Calculate the amount of heat, in calories, that must be added to warm 89.7 g

of brick (0.20) from 22.0 °C

to 44.1 °C.

Assume no changes in state occur during this change in temperature.

Answer 1

To calculate the amount of heat required, we need to use the specific heat capacity of brick which is 0.20 cal/g°C.

The formula for calculating heat is:

Q = m * c * ΔT

Where Q is the heat energy required, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature.

Substituting the values given:

m = 89.7 g
c = 0.20 cal/g°C
ΔT = 44.1°C - 22.0°C = 22.1°C

Q = 89.7 g * 0.20 cal/g°C * 22.1°C
Q = 394.926 cal

Therefore, the amount of heat required to warm 89.7 g of brick from 22.0°C to 44.1°C is 394.926 calories.
