Overview

Thermal energy is a form of energy associated with hotness and coldness. Heat can do work and also flows from a body at higher temperature to a body at lower temperature. Temperature measures the degree of hotness or coldness of a body and helps determine the direction of heat flow. Heating can caus

Key Concepts

Heat is a form of energy

Heat is a form of energy. Temperature is the degree of hotness or coldness of a body. Heat flows from higher temperature to lower temperature, so temp

J

J. P. Joule showed that work and heat are equivalent. One Calorie of heat is equivalent to 4.2 Joule of work. Work done against friction is always con

Clinical thermometers measure body temperature

Clinical thermometers measure body temperature, laboratory thermometers measure experiment temperatures, maximum-minimum thermometers record daily ext

The relation among the three scales

The relation among the three scales is (C)/(100) = (F-32)/(180) = (K-273)/(100). This allows conversion from one scale to another.

When a substance changes state

When a substance changes state, heat may be absorbed without a rise in temperature. Latent heat of fusion is the heat needed to convert 1 kg of a soli
