Is the following statement true or false?
Energy isn’t created or destroyed.
True
Flase
Fill in the blank with the correct term.
Energy isn’t created or destroyed it only __________.
transfers
disappears
gets lost
Choose the correct statement.
Please read carefully!!
Energy can be created and destroyed. Therefore, as energy disappears, it goes in one part of the system as it jumps in another part of the system.
Energy isn’t created or destroyed. Therefore, as energy transfers, it increases in one part of the system as it decreases in another part of the system.
Is the following statement true or false?
When two things are in contact, their molecules collide, and kinetic energy disappears from the faster-moving molecules to the slower-moving molecules.
True
False
Fill in the blanks with the correct terms.
When a thing gets hotter, its molecules are moving _______ and have _______ kinetic energy.
faster and have more kinetic energy.
slower and have less kinetic energy.
Fill in the blank with the correct term.
When the molecules of the air speed up, the air temperature _________.
decreases
increases
Choose the correct word to fill in the blank:
When the molecules of the air slow down, the air temperature _________.
decreases
increases
Fill in the blanks with the correct terms.
When a thing gets colder, its molecules are moving ______ and have ________ kinetic energy.
slower and have less kinetic energy.
faster and have more kinetic energy.
Is this statement true or false?
When things are in contact, the faster-moving molecules of the hotter thing transfer kinetic energy to the slower-moving molecules of the colder thing.
True
False
Fill in the blank with the correct term.
When one thing cools down, something else has to ______.
warm up.
cool down.
Choose the correct answer with the following options below:
When you turn on the Air Conditioner to cool down the inside of your hot house, what happens to the heat energy from the inside of the house?
The heat energy that was in those molecules disappear because I turned on the Air conditioner
It gets transferred to molecules in the air outside.
I know this because energy cannot be created or destroyed. Energy can only be transferred from one place to another
Is the following statement true or false?
Energy can only be transferred from one place to another
True
False
Fill in the blanks with the correct terms.
An air conditioner uses machines and chemicals to remove kinetic energy from the molecules that make up the air inside a room. This _______ the molecules ______ and _______ the room’s air temperature.
This slows the molecules down and lowers the room’s air temperature.
This increases the molecules up and increases the room’s air temperature.
Is the following statement true or false?
When two things of different temperature come into contact, the warmer one will always transfer energy to the cooler one.
True
False
Fill in the blank with the correct term.
Since energy can’t be created or destroyed, a change in temperature always means energy has been ________.
destroyed
created
transferred
Please read carefully and choose the correct option below.
If you touch a hot curling iron with your finger, will the body heat from your finger transfer into the hot curling iron OR will the hot curling iron transfer its heat into your finger? How do you know?
Disclaimer: This is a hypothetical question. Do not touch a hot curling iron.
The body heat from your finger will transfer to the hot curling iron because of your body heat.
The heat from the hot curling will transfer into your finger because whatever is hotter will always transfer its energy to the cooler one.
Nothing happens.
Fill in the blank with the correct sentence.
Energy can’t be created or destroyed, so we know ________________________________________.
it increases from one molecule to the other during the collision.
it’s just transferred from one molecule to the other during the collision.
it’s decreases from one molecule to the other during the collision.
Is the following statement true or false?
When two things are in contact, their molecules collide, and kinetic energy transfers from the faster-moving molecules to the slower-moving molecules.
true
false
Is the following statement true or false?
Energy is created or destroyed.
false
true
Fast moving molecules means
heat
cold
nothing
Slow moving molecules means
cold
heat
nothing
