Answer:
To calculate the amount of energy (in calories) required to raise the temperature of 53 grams of brass by 45°C, you can use the specific heat capacity of brass and the following formula:
Energy (calories) = Mass (grams) × Specific Heat Capacity (cal/g°C) × Temperature Change (°C)
The specific heat capacity of brass is typically around 0.090 J/g°C, which is equivalent to 0.0215 cal/g°C.
The mass of brass is 53 grams.
The temperature change is 45°C.
Now, plug these values into the formula:
Energy (calories) = 53 g × 0.0215 cal/g°C × 45°C
Energy (calories) = 53 g × 0.0215 cal/g°C × 45°C = 54.1575 calories
So, it would take approximately 54.16 calories of energy to raise the temperature of 53 grams of brass by 45°C.
