Calculating Heat Required to Raise the Temperature of Granite

Question:

How much heat is needed to raise a 0.060 kg piece of granite from 82°C to 212 °C?

Answer:

There are required 6162J to raise the temperature of the piece of granite from 82°C to 212°C.

Explanation:

Specific Heat Capacity: The specific heat capacity of granite is given as 0.790J/g°C.

To calculate the heat required, we can use the equation:

Q = m×C×ΔT

Where:

• Q is the heat in joules (J).
• m is the mass of the substance, which is 0.060 kg = 60.0g.
• C is the specific heat capacity, 0.790 J/g°C.
• ΔT is the change in temperature, which is 212°C - 82°C = 130°C.

Substitute the values into the equation:

Q = 60.0g × 0.790 J/g°C × 130°C

Therefore, the heat required to raise the temperature of the granite piece is 6162J.
