Statement 1: Radiation dryers are used to dry grains and reduce their moisture content before storage.Statement 2: Baking ovens are used both for making the dough and after that’s made, making biscuits by cutting them and baking them further. This entire process uses radiation.

Heat transfer can occur through conduction, convection, and radiation:   Conduction: Heat is transferred from the hotter end of an object to the colder end through physical contact. For example, when you touch a metal cooking pot in an air-conditioned room, your hand loses heat to the colder pot. Convection: Heat is transferred by the movement of a heated fluid, such as air or water. For example, in free convection, warm air or water rises and is replaced by cooler air or water. Radiation: Heat is transferred between objects without direct physical contact through electromagnetic waves.... Show more

Heat transfer can occur through conduction, convection, and radiation:
 

Conduction: Heat is transferred from the hotter end of an object to the colder end through physical contact. For example, when you touch a metal cooking pot in an air-conditioned room, your hand loses heat to the colder pot.
Convection: Heat is transferred by the movement of a heated fluid, such as air or water. For example, in free convection, warm air or water rises and is replaced by cooler air or water.
Radiation: Heat is transferred between objects without direct physical contact through electromagnetic waves. For example, the sun heats the earth through electromagnetic waves.
