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.
