Question

The specific heat of a substance is
0.215 j/g how much energy is required to raise the temperature of 20 g of the substance from 72°C to 88 degrees Celsius

Answer 1

The energy required to raise the temperature of 20 g of the substance from 72°C to 88 degrees Celsius is 7.26 joules. This can be calculated using the formula:

Energy = (mass) x (specific heat) x (change in temperature)

Energy = (20 g) x (0.215 j/g) x (16°C)

Energy = 7.26 joules
