Q

Why is there no such thing as cold?

Hint: use the kinetic molecular theory

A

The energy particles that is produced in heat never stops moving, they just slow down.

(Slower the energy, lower the heat.)

Q

Explain how heat flows.

A

Heat flows from object to object, from a hotter to cooler object while exchanging thermal energy until it has reached thermal equilibrium.

Q

What is the difference between heat and temperature?

A

Temperature measures how fast the energy particles are moving.

Heat is the motion of the molecules.

Remember: THEY ARE NOT THE SAME

Q

Define the use of Kelvin scale.

A

Kelvin scales are temperature scales that have an absolute zero (where temperatures don’t exist) and atoms don’t move at all.
