If temperature of a black body increases from 7°C to 287°C, then the rate of energy radiation increases by

Radiation is the transfer of energy through electromagnetic waves or particles without the need for a medium. It includes types like light, heat, and X-rays. Radiation can travel through a vacuum, unlike conduction or convection. It plays a vital role in energy transfer, climate processes, and various technological applications.

Class 11 Physics Chapter 10 Thermal Properties of Matter explains the concepts of temperature heat and specific heat capacity. It covers thermal expansion calorimetry and the transfer of heat through conduction and convection. The chapter also discusses the laws of thermodynamics and the behavior of gases in different temperature and pressure conditions.
