Question

The specific heat of palladium is 0.239 J/g°C. How much heat (q) is released when a 10.0 g piece of platinum cools from 100.0°C to 50.0°C?

Answer 1

Answer:

119.5 J

Explanation:

First we calculate the temperature difference:

• ΔT = 100 °C - 50 °C = 50 °C

Then we can calculate the heat released by using the following formula:

• q = Cp * ΔT * m

Where q is the heat, Cp is the specific heat, ΔT is the temperature difference and m is the mass.

We input the data:

• q = 0.239 J/g°C * 50 °C * 10.0 g

• q = 119.5 J
