Question

Which of the following correctly differentiates heat from temperature?

पर्याय

• Heat is a scalar quantity; temperature has dimensions [M¹L²T⁻²]

• Heat flows from cold to hot; temperature flows from hot to cold

• Heat is energy in transit due to a temperature difference; temperature measures the degree of hotness

• Heat is measured in Kelvin; temperature is measured in Joules

Answer 1

Heat is energy in transit due to a temperature difference; temperature measures the degree of hotness

Explanation:

Heat is the form of energy exchanged between bodies due to a temperature difference, while temperature is a physical quantity that defines the thermodynamic state of a system and measures how hot or cold a body is. They are fundamentally different concepts, though closely related.
