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

Raising its temperature by 1 C

Step-by-step explanation:

A P E X

Answer 2

Raising its temperature by
`1^(\circ)C`

Step-by-step 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
