Physics Notes(Heat Transfer)

Chrispen Test

Thermal Energy

How fast particles and molecules move in an object. The total amount of movement in a substance.

Temperature

A measure of the average kinetic energy of particles in a substance, indicating how hot or cold it is.

Temperature Scales

Celsius and Fahrenheit

Equation for Fahrenheit to Celsius

C= 5/9(F-32)

Fahrenheit to Celsius - 75 f

C = 23.9 c

Heat

The form of energy that is transferred between systems or objects.

3 types of heat transfer

conduction, convection, radiation

Radiation

The transfer of heat through electromagnetic waves. (Cannot see it)

Examples of Radiation

infrared heaters, sunlight, microwaves

Conduction

The transfer of heat through direct contact between materials, where energy moves from hotter to cooler regions.

Examples of Conduction

metal rod heating in fire, cooking on a stovetop, warming of a skillet by direct contact with hot burners

Convection

The transfer of heat through the movement of fluids (liquids or gases), where warmer, less dense areas rise and cooler, denser areas sink, creating a circulation pattern.

Examples of Convection

The process of heat transfer involving the circulation of fluids, such as boiling water or warm air rising in a room.
