GCSE Physics - Specific Latent Heat #29

The video tutorial explains specific latent heat and its role in state changes of substances. It covers how energy is used during melting and boiling, and introduces the concepts of specific latent heat of vaporization and fusion. The tutorial uses graphs to illustrate temperature changes during state transitions and provides a practical example with water. It concludes with the equation for calculating specific latent heat, emphasizing that energy is required or released during state changes without temperature change.

What happens to the internal energy of particles as a substance is heated?

Explain the significance of temperature in relation to the internal energy of particles.

Describe what occurs during a change in state when heating a substance.

What is specific latent heat and how is it defined?

Differentiate between specific latent heat of vaporization and specific latent heat of fusion.

How does the energy required to change the state of a substance relate to its mass?

Calculate the energy required to completely boil 2.5 kilos of water at 100°C using specific latent heat.
