Heat and Heat Technology
Heat is a form of energy that can be transferred from one object to another. It is a crucial concept in science and plays a significant role in various technological applications.
Key Concepts
- Temperature: A measure of the average kinetic energy of the particles in a substance. It determines the direction of heat transfer - from hot to cold.
- Heat Transfer: The movement of heat from a warmer object to a cooler object. There are three main methods of heat transfer: conduction, convection, and radiation.
- Thermal Expansion: The tendency of matter to change in shape, area, and volume in response to a change in temperature.
- Specific Heat: The amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.
- Heat Technology: The application of scientific principles for practical purposes related to the transfer, storage, and use of heat.
