What happens to particles when they are heated?
They move more and the spaces between the particles increases.
Give an example of a good conductor.
Metal, carbon
Give an example of a bad conductor.
Plastic, wood, glass
What name is given to a material that does not allow thermal (heat) energy to be transferred through it easily?
An insulator
What name is given to a material that allows thermal (heat) energy to be transferred through it easily?
A conductor.
What are the units for measuring temperature?
Degrees Celsius (°C)
What is heat transfer?
When thermal (heat) energy moves from an area/object of higher temperature to an area/object at a lower temperature.
What is the unit for measuring thermal (heat) energy?
Joules (J)
Which piece of equipment is used to measure temperature?
A thermometer
A graph that shows the temperature of an object as it cools down is called…
A cooling curve
The ‘average’ movement of atoms in an object determines the…..
Temperature (of the object).
The ‘Total’ movement of atoms in an object determines the…..
Thermal (heat) energy.
How do you calculate and average?
Add them all up (Total) then divide by the number of values.
What are the controlled variables in an experiment?
Everything that is kept the same in order to make your experiment fair/valid.
How do we calculate a percentage change (increase or decrease)
Difference (between 2 numbers) / Original number x 100
What is a hypothesis or prediction?
What you think is going to happen in an experiment. The results you are expecting.
What should we remember next to our labels in a table?
(The units)
