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
Andrej [43]

Answer:

119.5 J

Explanation:

First we <u>calculate the temperature difference</u>:

  • ΔT = 100 °C - 50 °C = 50 °C

Then we can <u>calculate the heat released</u> 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 <u>input the data</u>:

  • q = 0.239 J/g°C * 50 °C * 10.0 g
  • q = 119.5 J
