Class 11Physics1 Thermal Properties of Matter: Thermometry, Expansion and CalorimetryLatent Heat and Heating Curve
Easy$A$ metallic ball and a highly stretched spring are made of the same material and have the same mass. They are heated so that they melt. The latent heat required:
- Ais the same for both.
- Bis greater for the ball.
- Cis greater for the spring.
- Dfor the two may or may not be the same depending upon the metal.
