Particle Motion
This type of energy is measured with temperature.
What is Kinetic Energy
The three states of matter focused on most in class.
Solid, Liquid, Gas
This type of heat transfer occurs when heat moves in electromagnetic waves through empty space.
Radiation
The amount of heat needed to raise the temperature of a 1kg piece of material by 1 degree Celsius
specific heat
True or false: The average kinetic energy of particles increases as the temperature increases.
true
Movement of materials from an area of high concentration to a low concentration.
What is diffusion?
Changing from a gas to a liquid because of cooling.
What is condensation?
This type of heat transfer occurs when heat moves in cycles through a fluid such as gas or liquid.
Convection
another term for heat
thermal energy
True or false: The average kinetic energy of particles in a substance never changes.
false
Most materials do this when they are heated.
What is expand?
Changing from a solid to a liquid because of heating.
What is melting?
This type of heat transfer happens when something hot directly touches something cool.
Conduction
These materials allow heat to move easily through them.
thermal conductors
True or false: If the same quantity of thermal energy is added to two different substances with the same mass, the substance with the lower specific heat will experience less of a temperature change.
False
What is matter?
This type of vaporization happens inside a liquid.
What is boiling?
During conduction, when a hot item touches a cool item, they eventually become the same temperature. This is called:
thermal equilibrium
These materials do not allow heat to travel through them easily.
Thermal insulators
What type of heat transfer happens when you get a sunburn during a baseball game?
Radiation
The rate of diffusion speeds up when this happens to a material.
When two phases are present on a heating curve, the temperature of the material does this.
Remains the same.
Tell two properties that affect how quickly something heats up.
surface area, thickness, reflectivity, absorption, mass
What type of heat transfer happens when a hot-air balloon is flown?
Convection
