Temperature is a physical quantity that expresses the degree of hotness or coldness of a substance. It is measured using a thermometer and is usually expressed in Celsius, Fahrenheit or Kelvin. Temperature affects various physical properties of matter, such as its state, volume and thermal energy.
Class 11 Physics Chapter 10 Thermal Properties of Matter focuses on heat and temperature. It covers concepts like thermal expansion heat capacity specific heat and thermal conductivity. The chapter also discusses the laws of thermodynamics and methods of heat transfer including conduction convection and radiation with practical examples and applications.
Temperature is the average kinetic energy of the particles in a substance. It tells how hot or cold an object is and determines the direction of heat flow. Heat flows from a body at higher temperature to a body at lower temperature until thermal equilibrium is achieved.
