Which is the best example of a physical change?
convection
water vapor changing into liquid water
Heat energy in the nail will flow into the cold water.
the wagon with 20 kilograms of sand
water in a cup turning into ice
The object moves at a constant speed from 0 s to 5 s.
the distance the object moves and the time it takes to move that distance
because the heat of the sun caused the plastic to expand
