Question

The specific heat of a substance is 0.215 how mushkil energy is required to raise the temperature of 20 g of the substance from 72 to 88

Answer 1

To calculate the energy required to raise the temperature of a substance, you can use the formula:

Energy = mass * specific heat * change in temperature

Given:
Specific heat (C) = 0.215 cal/g°C
Mass (m) = 20 g
Change in temperature (ΔT) = 88°C - 72°C = 16°C

Substituting the given values into the formula:

Energy = 20 g * 0.215 cal/g°C * 16°C

Energy = 68.8 cal

Therefore, it requires 68.8 calories of energy to raise the temperature of 20 g of the substance from 72°C to 88°C.
