Question

The specific heat capacity of a substance is the amount of energy associated with doing which of the following to 1kg of the substance?

Answer 1

Answer:

Raising its temperature by $1^{\circ}C$

Explanation:

The specific heat capacity of a substance is defined as the amount of energy needed to raise the temperature of 1 kg of a substance by $1^{\circ}C$.

The specific heat capacity of a substance essentially tells us how much energy is needed to heat the substance: the larger it is, the more energy is needed. The amount of energy needed to increase the temperature of a substance is given by

$Q=mC_s \DeltaT$

where

m is the mass of the substance

Cs is the specific heat capacity

$\Delta T$ is the temperature variation of the substance
