Critical Thinking
A can of pop has been in a hot car all day. Describe what happens in terms of energy transfer.
Air transfers kinetic energy to pop until equilibrium is reached.
A number that summarizes a set of data is the ______
Average
Water is an example of this because it is made of 2 atoms of Hydrogen and 1 atom of oxygen.
molecules
When an object has greater kinetic energy, it is said the molecules have this speed.
Faster
What day is Easter this year?
April 5th
Water freezes in a freezer into ice cubes. Describe what happens in terms of energy transfer.
Fridge takes energy from the water and transfers it out to the air.
This is the total amount of kinetic energy an object or system has.
Thermal energy
The following 3 molecules are moving at speeds 1, 2, and 3. Their temperature is ___
2
When water freezes in a freezer, this is what has happened to the energy of the molecules of water.
Decreased
What is the most common atom/element in the universe?
Hydrogen
What is the total thermal energy of an object that has a temperature of -459 F, -273 C, or zero Kelvin?
0
a set of interacting parts forming a complex whole
System
This is how molecules are able to transfer energy from one object to another.
colliding / collision
Energy is not created or destroyed. Instead, it does this.
Transfer
What the second largest planet in the Solar System?
Saturn
I go to the beach and fill a fishbowl with water from the Pacific Ocean. Tell me in terms of energy what the fishbowl and the ocean have in common and what is different.
Same temperature, ocean has MUCH more thermal energy.
Temperature is a measure of __________ kinetic energy.
average kinetic energy
This is how to calculate the average kinetic energy of a substance.
total kinetic energy DIVIDED by the number of molecules
Lisa melted a candle to make an art project. Then, she placed the project by a fan to cool it off. This is the direction that energy is transferring.
From candle to air (from faster/ hot to slow/ cold molecules)
The largest organ of the human body is.
What is skin?
My energy transfer lab reached equilibrium, but then steadily got colder. Why?
Molecules transfer energy until they reach this stable state.
Equilibrium
Find the average kinetic energy.
3 2 2 2 3
3 2 1 2 1
1 3 3 1 1
