This can be found by adding all of the numbers to get a total and then dividing by the number of numbers that were added.
What is Average?
The greater kinetic energy an object have, the _________ its molecules are moving.
What is faster?
A can of soda has been in a hot car all day. The temperature of the soda has gotten hotter, so this is what has happened to the energy of the molecules in the soda can.
What is "They have increased/gotten faster"?
Or What is "they have gained energy"?
Energy is neither created nor destroyed, it transfers.
What is true?
When something becomes different over time, it is known as this.
What is change?
This is the type of energy that an object has because it is moving.
What is Kinetic Energy?
When objects get colder, the molecules move at a _________ speed.
What is slower?
When water freezes in a freezer, this is what has happened to the energy of the molecules of water.
What is "They have decreased/slowed down"?
Or What is "They have lost energy"?
In order for substances to reach equilibrium, both of the objects have to transfer temperatures back and forth.
What is false? (Hot substances transfer to colder)
Thermal energy is a measure of this type of energy
What is total kinetic energy?
This is a measure of how hot or cold something is.
What is temperature?
Energy is not created or destroyed. So how does an object "lose" energy?
What is it transfers its energy to an object with less?
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.
What is "from the art project to the air".
Or What is "from hot to cold."
The hotter something is, the slower its molecules move.
What is false? (they move faster)
Find the average kinetic energy
What is average kinetic energy is 2?
This is when something stays mostly the same over time.
What is stability?
Temperature is a measure of the ____________.
What is average kinetic energy?
This is the system that was chosen as the best option to warm up the air in Riverdale school.
What is "the groundwater system"?
When two substances start at the same temperature, the substance with a smaller amount of molecules will gain or lose heat at a faster rate than the substance with a larger amount of molecules.
What is true?
This is how molecules are able to transfer energy from one object to another.
What is collision/colliding?
This is the balanced state in which a system is stable, such as when two or more samples are at the same temperature.
What is equilibrium?
Molecules transfer energy until they reach this state.
What is equilibrium?
You have a bowl of soup and a cup of soup. Both are the same temperature. You bring both of them to school. Which one will get cold quicker?
What is the cup of soup?
Thermal energy is the average kinetic energy of a substance
What is false?
This is how to calculate the average kinetic energy of a substance.
What is total kinetic energy DIVIDED by the number of molecules?
