Chapter 5 Flashcards
The total kinetic energy of all the particles in a substance
The 2 factors that affect Thermal Energy
1.) How much of a substance/particles
The energy transferred between objects of different temperatures; energy transfers in one direction, hot to cold
The measure of the average kinetic energy of particles in substance.
Celsius, Fahrenhiet, Kelvin
The tranfer of energy from direct contact; from one form of matter to another when particles collide
The transfer of energy through a liquid or a gas
When particles in a hot liquid or gas speed up, spread out, becomes less dense and rises; then particles cool, slow down, becomes more dense, and sinks.
The transfer of energy through electromagnetic waves through a space
Material which transfers heat easily; metal
Material which reduces or prevents the tranfer of heat; cloth, rubber, wood
When particles in a substance heat up, speed up, spread out and expand
