Question 1 Report

Heat transfer by convection in a liquid is due to the

translatory motion of the molecules of the liquid

increased vibration of the molecules of the liquid about their mean positions

expansion of the liquid as it is heated

latent heat of vaporization of the liquid

ability of the liquid to evaporate at all temperatures

Answer Details

Heat transfer by convection in a liquid is due to the translatory motion of the molecules of the liquid. When a liquid is heated, the molecules gain kinetic energy and move faster, which results in the formation of convection currents. These currents carry the heat energy from one point to another in the liquid. As the heated liquid rises, it transfers the heat to the surrounding cooler liquid molecules by collisions, causing the cooler liquid to become less dense and rise as well. This creates a continuous cycle of rising and sinking of the liquid, which transfers heat throughout the liquid. This process is known as convection, and it is the main mechanism of heat transfer in fluids like liquids and gases.
