Question

what is effusion and diffusion. value of latent heat of fusion​

Answer 1

Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy.

Effusion refers to the movement of gas particles through a small hole.

Graham's Law states that the effusion rate of a gas is inversely proportional to the square root of the mass of its particles.

latent heat of fusion

While ice melts, it remains at 0 °C (32 °F), and the liquid water that is formed with the latent heat of fusion is also at 0 °C. The heat of fusion for water at 0 °C is approximately 334 joules (79.7 calories) per gram, and the heat of vaporization at 100 °C is about 2,230 joules (533 calories) per gram.
