Vedclass · Answer

(A) There are three primary modes of heat transfer: $1$. Conduction: This requires physical contact between bodies. $2$. Convection: This requires a material medium (liquid or gas) to transfer heat. $3$. Radiation: This involves the emission of electromagnetic waves and does not require any material medium. Since the bodies are kept in a vacuum,conduction and convection cannot occur. Therefore,the hot body loses heat to the cold body through radiation,causing its temperature to decrease.

$A$ hot and a cold body are kept in vacuum separated from each other. Which of the following causes a decrease in the temperature of the hot body?
