b. the particles in fluid can easily flow that enables it to transfer energy.

convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. heat energy is transferred from hot places to cooler places by convection. liquids and gases expand when they are heated.
