Final answer:
To calculate the specific heat required to raise the temperature of granite by 10 °C or 20 °C, we need to know the specific heat capacity of granite. Without this information, we cannot provide an exact answer. However, using a typical value for the specific heat capacity of granite, we can estimate the heat required for both temperature increases.
Step-by-step explanation:
To determine the specific heat required to raise the temperature of 1 gram of granite by 10 °C or 20 °C, we need to know the specific heat capacity of granite. However, this information is not provided in the question. If we had the specific heat capacity (let's denote it as C), the amount of heat (Q) required would be calculated using the equation Q = m × C × ΔT, where:
- m is the mass of the granite,
- C is the specific heat capacity of granite,
- ΔT is the change in temperature.
For a mass of 1 gram (0.001 kg) and a temperature change of ΔT = 10 °C or 20 °C, we would plug these values into the equation to calculate the specific heat required. Without the value for the specific heat capacity of granite, we cannot complete this calculation.
As an example, if the specific heat capacity of granite was 790 J/kg °C (a typical value for granite), then for a 10 °C temperature increase, the heat required would be Q = 0.001 kg × 790 J/kg °C × 10 °C = 7.9 J, and for a 20 °C increase, it would be Q = 0.001 kg × 790 J/kg °C × 20 °C = 15.8 J.
