What are units for heating capacity? Mark all that apply: a) - Tons b) - kJ/kg c) - kW d) - Btu

(b) kJ/kg

Explanation:

The ratio of amount of energy required to change the temperature of the substance by certain magnitude and this magnitude of temperature change is known as heat capacity of the substance.

The expression for Heat capacity is:

C=E/ΔT

Where,

C is the Heat capacity

E is the energy absorbed/released

ΔT is the change in temperature

The SI unit of heat capacity is J/K.

(a) Tons represents the unit of mass (1000 kg)

(c) kW represents the unit of power (1000 W)

(d) Btu represents the unit of heat (1055 J)

The units from the options that can be a unit of heat capacity is (b) kJ/kg.
