Q1-Week 4-5 SCIENCE 8

Heat

by Teacher Gerazel

Temperature​

-is the measure of kinetic energy​

​KINETIC MOLECULAR THEORY

​Explains that all the body area in constant motion

​SOLID

​GAS

​LIQUID

INTERNAL ENERGY​

To achieve greater internal energy you need to have a higher temperature and greater volume​

ENERGY FLOW​

​​Conduction

It is a mode that requires a material medium for the transfer of heat.

​CONVECTION

​This is the process by which heat energy is transferred in the liquid fluid by the actual movement of the heated molecule of particles.

​RADIATION

​It is the only mode of heat transfer that does not require a material medium. Radiation is energy emitted by matter in the form of electromagnetic waves.

​The behavior of particles when heated or cooled

​Heated- excites /expands

​Cooled- unexcited/ shrinks

​Coefficient Linear Expansion

​The fraction by which a material expands or contract for every degree increases or decreases

​Specific Heat Capacity

​Is the amount that would change the temperature of matter a degree higher or lower

LATENT HEAR CAPACITY​

is the amount of heat needed to change the state of matter at a specific temperature​
