Question

The amount of heat required to raise the temperature of 1 gram of substance through 1°C is known as ________

(a) Internal energy

(b) Molar heat capacity

(c) Specific heat

(d) Heat enthalpy

This question was addressed to me in class test.

Asked question is from I.C Engine in chapter Internal Combustion Engine of Farm Machinery

Answer 1

The correct option is (c) Specific heat

Explanation: The relationship between heat and temperature change is usually expressed in the form

Q=cm∆T

Where c is the specific heat. The relationship does not apply if a phase change is encountered, because the heat added or removed during a phase change does not change temperature.
