What is temperature?
The measure of the average kinetic energy of the particles of a substance
True or false, the average kinetic energy of the particles increases as the temperature
True
Why does running hot water of a metal jar make it easier to open?
It expands
Kinetic energy is the energy of_____
motion
When a substance is cooled, it expands.
False
Substances with a lower specific heat will experience less of a temperature change. True or false?
False
When a pot of water is put on a stove, the water at the surface gets hot, why?
convection
Give an example of a thermal conductor
Metal, carbon, aluminum, etc.
Give an example of an insulator
wood
How is heat transferred between a hot and cold object by conduction?
The particles of the hotter object transfer kinetic energy to the particles of the cooler object
Compare hot tea and an iceberg in terms of temp and thermal energy
Tea is hotter, iceberg has more thermal energy
If you jump into water on a hot summer day and the water is cold, that is because___-
water has a high specific heat
Do most metals have a lower specific heat
yes
Most materials do what when heated?
expand
What temp are the particles moving the fastest in a pencil?
50
High specific heat is what?
requires more thermal energy to change the temp
