Matter is made up of _____________.
tiny particles, called (atoms)
What is thermal energy?
A measure of how many particles there are and how fast they are moving.
Describe what happens to particles when the temperature increases
particle contract and move slower
What is conduction?
The transfer of thermal energy through direct contact.
Gases have ________ spaces between particles.
large.
The particles are always _________.
moving
What is heat?
the transfer of thermal energy.
What is an insulator?
Keeps thermal energy in.
What is convection?
The transfer of thermal energy by the movement of matter; this happens in gasses and liquids; WARM MATTER RISES AND COOLER MATTER SINKS; this makes gas and liquid flow in a pattern
Liquids have ________ space between particles
some (in between solid and gas)
When we heat them, the particles ___________.

What unit do we measure temperature by in Canada?
Degree Celsius
What is a themostat?
something used to control heating systems and the transfer of thermal energy.
What is radiation?
thermal energy is transfered through waves.
What happens when you remove thermal energy from a gas?
You get a liquid.
The particles ______________________.
have spaces between them.
According to science, when I ask someone to heat my leftover pasta, what am I really saying?
May you add thermal energy to my pasta, please?
How does a thermostat work?
When a bimetallic strip is heated, one metal expands faster than the other. The strip bends to hit a switch and control the temperature.
convection currents
