Temperature
This is a measure of the average kinetic energy of particles of matter
What is temperature?
This includes both the kinetic and potential energy of a system.
What is thermal energy?
This is the direction that heat flows.
Where are areas of high temperature to areas of low temperature?
When two objects in contact have the same temperature it is called this.
What is thermal equilibrium?
This is how the speed of particles in a bowl of hot soup compares to those in a cup of cool water.
What is the particles move faster?
This is the reason that a swimming pool full of cold water would have more thermal energy than a cup of boiling tea.
What is the pool has more water particles?
This is the reason metal would transfer heat faster than a gas.
What is metal is a better conductor than a gas?
This is what happens to a hot cup of coffee that is left on a table over time.
What is that it cools down until it reaches thermal equilibrium with the room temperature?
This is what happens to particle speed as temperature decreases.
What is: particles move more slowly?
This is how the state of matter affects thermal energy.
What is: gases have the most thermal energy, liquids have less, and solids have the least?
This is how heat transfer occurs between particles.
What are particle collisions?
The sun warms your skin even though it’s millions of miles away. This is an example of this type of heat transfer.
What is radiation?
All particle motion stops at this temperature.
What is absolute zero (or 0o Kelvin)?
This is the difference between temperature and thermal energy when it comes to mass.
What is: temperature does not depend on mass, but thermal energy does depend on mass.
This is the reason that a cold object FEELS cold when you hold it.
Why does heat transfer out of your hand and into the the cold object?
This type of heat transfer is shown when hot soup circulates in a pot on the stove.
What is convection?
This is how temperature relates to kinetic energy.
What is high temperature = high kinetic energy? (Or what is low temperature = low kinetic energy?)
Thermal energy depends on these 3 factors.
What are: the mass of the system, the state of matter, and the substance it's made of?
These two factors determine how quickly heat can flow.
What are the differences in temperature and the substances involved?
You burn your feet walking barefoot on hot sand. The sand heated your feet through this method.
What is conduction?
