Science chapter 3 test review.

What is absolute Zero?

• Coldest possible temperature.

  Zero molecular movement

• When the molecules move very fast

• When the molecules move very slow

• when the molecules are not there

Does oil warm up faster than water?

• I don't know

• No, water is easier to heat up

• Yes, it takes less energy to warm oil

• No, oil is harder to trasnfer energy

What are molecules?

• The total energy

• The kinetic energy

• They are clumps of energy

• Groups of atoms put together

Do all molecules move the same?

• Yes, they all move the same

• No, they will move based on if it is cooler(slower)/warmer(Faster)

• No, Molecules don't move

• No, It depends on the amount of molecules

What is Total kinetic energy?

• The total and dividing it by the number of the total molecules present

• It is the energy in molecules.

• It is the energy that is transfered.

• Total kinetic energy is all the kinetic energy added together.
