NCERT Solutions for Class 7 Science Chapter 3: Heat – Education85
This chapter is all about heat, the energy that flows between objects due to a temperature difference. Here’s a quick breakdown:
Heat Transfer: Heat always moves from a hotter object to a cooler one until they reach the same temperature.
The Three Amigos: There are three main ways travels:
Conduction: Direct touch! Think of a metal spoon getting hot in hot soup.
Convection: Movement of fluids (liquids and gases). Hot air rises, cooler air sinks (like sea breezes).
