Question

What is the specific heat of a substance that has a mass of 15.0 g and requires

60.0 calories to raise its temperature by 25.0°C?*

Answer 1

0.16 cal/g°C

Step-by-step explanation:

The following data were obtained from the question:

Mass (M) = 15 g

Heat (Q) = 60 calories

Temperature change (ΔT) = 25 °C

Specific heat capacity (C) =..?

We, can obtain the specific heat capacity of the substance as shown below:

Q = MCΔT

60 = 15 × C × 25

60 = 15 × 25 × C

60 = 375 × C

Divide both side by 375

C = 60/375

C = 0.16 cal/g°C

Therefore, the specific heat capacity of the substance is 0.16 cal/g°C
