1-How conduction is occurred in gases and liquids?

Solutions

Expert Solution

Conduction in liquids:
During conduction, heat always transfers from the hotter body to the colder body. Temperature is a reflection of the average kinetic energy of the particles of a substance. As the temperature increases, the kinetic energy of the fluid particles also increases. This causes the particles to vibrate. During this vibrations of particles, the warmer and faster particles collide into cooler and slower particles. When this occurs, energy is moved from the warmer particles that have more energy to the cooler particles that have less energy. This process continues until the system attains equilibrium and both objects have the same temperature.

Conduction in gases:

Conduction in gases is mainly due to the molecular momentum and thermal diffusion which is caused by collisions between the particles. Hotter particles have high kinetic energy and they move in random directions during this movement they collide with cooler particles and lose some energy and hence transfer some heat to cooler particles and they slow down. This process continues umtill all the particles attain same temperature.
