Lesson 1: Particles in Motion
Kinetic Energy
State of matter with a definite shape and volume. Particles are packed and vibrating in place
Solid
Heat moves from ______________ to ______________
Warmer/hotter objects to cooler objects
The amount of heat required to raise the temperature of of 1kg of a substance by 1 degree celcius
Specific Heat
A system that does not exchange matter or energy with the environment
Close System
Random Motion
State of matter with no definite shape or volume. Particles are moving free and fast
Radiation
Materials with higher specific heat experience ________ temperature change
Less
Is a system that exchanges matter or energy with the environment
Open System
What is temperature the measure of?
Average kinetic energy
State of matter with no definite shape but has a definite volume. Particles are flowing.
Liquid
When two materials that are in contact have the same temperature, they are said to be in...
Materials with low specific heat experience ________ temperature change
Greater
Material through which thermal energy flows easily
Thermal Conductor
When temperature increases, what happens to average kinetic energy?
It also increases
The change in state of a liquid to a gas
Vaporization
When you pour hot water in a mug and the mug gets hot, this is an example of _____________?
Conduction
The object that provides the energy that is transferred
Source Object
Thermal Insulator
Temperature, Kinetic Energy, and Particle Motion have what type of relationship?
Equal or proportionate
There are two types of vaporatization? What are they?
Evaporation (ie. steam) and Boiling (ie. bubbles)
This type of energy transfer is responsible for the movement of Magma in Earth's interior.
Convection
The object that gains the energy that is transferred
Reciever Object
Thermal Energy
