Matter
The 3 states of matter.
Definition of heat.
Definition of thermal energy.
Total amount of energy (speed and mass)
Definition of temperature.
measurement of average thermal energy.
Device used to measure temperature.
Thermometer
Vibrate
The way heat moves.
Hot to cold.
Two things thermal energy depends on.
Mass and Kinetic Energy (movement and amount)
Celsius, Kelvin and Fahrenheit
This person made improvements on the glass thermometer
Anders Celcius
Definition of Kinetic Energy
Energy of Motion
which has more thermal energy: solid or liquid? and why?
liquid, more kinetic energy of particles
Relationship between thermal energy and amount of molecules.
Thermal energy increase, amount of energy increase
Definition of Absolute Zero
lowest temperature possible
Type of device used to measure temperature over a long period of time.
Recording thermometer
Matter changes states of matter when _______ is absorbed.
Heat or Thermal Energy
which has more thermal energy: glacier or campfire? and why?
glacier, more mass
Relationship between thermal energy and kinetic energy
Thermal energy increase, kinetic energy increase
Beaker A has 250 ml of water at 30 degree Celsius
Beaker B has 100 ml of water 80 degree Celsius
Which beaker has more total energy, and which has more average energy?
Beaker A - More Total Energy
Beaker B - More Average Energy
An electrical signal is generated when the coiled metal joints of this device are heated or cooled
Thermocouple
What are 3 of 5 parts of the particle theory of matter
All substances are made of tiny particles too small to be seen.
Each substance has unique particles
The particles are always in motion
When heat is added to a substance, the particles move faster. When heat is lost from a substance the particles move slower.
Particles are held together by attractive forces
What heat does, but thermal energy does not.
Transfer
Relationship between kinetic energy, thermal energy and temperature.
Kinetic energy increase, Temperature increase, Thermal energy increase
Absolute Zero in Kelvin is 0, what is it in Celcius? (Hint: to the decimal point)
-273.15 °C
1. No fixed volume or shape, not rigid
2. Rigid, fixed shape and volume
3. No fixed shape, not rigid, but fixed volume
Name all 3 in order
Gas, Solid, Liquid
