Study Notes
Heat Energy and Temperature
- Heat energy is the transfer of energy from one body to another due to a difference in temperature.
- Temperature is a measure of the average kinetic energy of particles in a substance.
Molecular Movement
- In gases, molecules are in constant random motion, and their motion increases as the temperature increases.
Insulators and Heat Transfer
- Insulators are materials that reduce heat transfer, such as fiberglass, wool, and wood.
- Convection is the primary mechanism of heat transfer in fluids such as bodies of water and gases.
Heating and Cooling Systems
- Radiators are effective in heating houses because they use convection currents to transfer heat from the radiator to the surrounding air.
- In the summertime, light-colored clothing is preferred to help regulate body temperature because it reflects more sunlight and heat than dark-colored clothing.
Factors Affecting Heat Transfer
- The amount of heat energy transferred depends on the temperature difference, surface area, and time of contact between the bodies.
- The amount of heat transferred is directly proportional to the mass of the system.
