To calculate the amount of heat energy required to raise the temperature of 100 g of copper from 20°C to 70°C, we can follow these steps: ### Step 1: Convert mass from grams to kilograms The mass of copper is given as 100 g. Since the specific heat capacity is in kg, we need to convert grams to kilograms. \[ \text{Mass (m)} = 100 \text{ g} = \frac{100}{1000} \text{ kg} = 0.1 \text{ kg} \] ...
