Heat energy flowsa)from body at higher temperature to body at lower te...
Explanation:
Heat energy is a form of energy that flows from a body at a higher temperature to a body at a lower temperature. This flow of heat energy continues until both bodies reach a state of equilibrium or equal temperature. The direction of the flow of heat energy is always from a body at higher temperature to a body at lower temperature. This is known as the second law of thermodynamics. Heat energy can flow through three different modes: conduction, convection, and radiation.
Conduction:
Conduction is the transfer of heat energy between two objects in direct contact with each other. In this process, heat energy flows from a body at a higher temperature to a body at a lower temperature until both bodies reach the same temperature. For example, when we touch a hot object, heat energy flows from the hot object to our hand until both reach the same temperature.
Convection:
Convection is the transfer of heat energy through a fluid (liquid or gas). In this process, heat energy flows from a body at a higher temperature to the fluid and then to a body at a lower temperature. For example, when we boil water in a pot, heat energy is transferred from the stove to the water through convection.
Radiation:
Radiation is the transfer of heat energy in the form of electromagnetic waves. It does not require any medium and can occur through a vacuum. In this process, heat energy flows from a body at a higher temperature to a body at a lower temperature. For example, the heat energy from the sun reaches the earth through radiation.
Therefore, the correct option is 'A' which states that heat energy flows from a body at a higher temperature to a body at a lower temperature.
