change ; stay
A device that measures temperature.
As energy in the form of heat is added to an ice cube, it begins to melt. What causes melting.
Heat causes the molecules to expanded and forces them apart.
Heat removes thermal energy from the ice cube and causes it to become liquid water.
Adding energy causes the bonds between the hydrogen and oxygen in the ice cube to break.
The transfer of thermal energy to the ice cube causes its molecules to move faster.
Which of these processes is the result of the motion of particles in a gas or liquid?
conduction
convection
insulation
radiation

conduction
convection
radiation
transformation

air was added to the system
heat was added to the system
water was added to the system
particles were added to the system
How does heat transfer when you hold an ice cube in your hand?
from the cold ice cube to your warm hand
the cold ice cube makes your hand cold
from your warm hand to the cold ice cube
very carefully
