Heat Energy

Heat energy is a form of energy that is transferred between objects due to a difference in temperature. It is the energy that causes the sensation of warmth and can be transferred through conduction, convection, and radiation.

Forms of Heat Transfer

• Conduction: The transfer of heat energy through direct contact between particles of a substance.
• Convection: The transfer of heat energy through the movement of fluids (liquids or gases) due to differences in density.
• Radiation: The transfer of heat energy through electromagnetic waves, such as sunlight or infrared radiation.

Effects of Heat Energy

Heat energy can cause changes in the state of matter, such as melting, evaporation, and sublimation. It also plays a crucial role in various natural processes, including weather patterns, the water cycle, and the distribution of heat on Earth.
