Q:

Q = mcdT refers to

A) Enthalpy formula B) Heat Transfer formula
C) Specific Heat formula D) Heat of Vaporization
 
Answer & Explanation Answer: C) Specific Heat formula

Explanation:

Q = mc∆T refers to Specific Heat formula.

 

When heat energy is added to a substance, the temperature will change by a certain amount.

The relationship between heat energy and temperature is different for every material, and the specific heat is a value that describes how they relate.

 

Q = mc∆T

 

Q = heat energy (Joules, J)

m = mass of a substance (kg)

c = specific heat (units J/kg∙K)

∆T = change in temperature (Kelvins, K)
