Answer:

To calculate the amount of heat energy required to raise the temperature of 200 grams of copper from 20°C to 70°C, we can use the formula:

Heat energy = mass × specific heat capacity × change in temperature

Given:

Mass = 200 grams = 0.2 kilograms

Specific heat capacity of copper = 390 J/kg°C

Change in temperature = 70°C - 20°C = 50°C

Using the formula, we can calculate the heat energy:

Heat energy = 0.2 kg × 390 J/kg°C × 50°C = 3,900 J

Therefore, the amount of heat energy required is 3,900 joules.

Answer:

Heat energy = mass × specific heat capacity × change in temperature

The amount of heat energy required is 3,900 joules.
