Why will these ice samples not melt at the same rate even when they are exposed to the same amount of heat?
Adding heat will increase the kinetic energy at different rates b/c of mass
Adding heat will increase the kinetic energy at the same rate b/c of mass

What happens to molecules when their kinetic energy decreases?
they move faster
they get heavier
it would depend on the type of molecule
they move slower

Two substances were in liquid form and got energy transferred out. Substance 1 changed, but substance 2 didn't. Why?
substance 1 had stronger attraction; molecules now move away from each oth
substance 1 had weaker attraction; molecules now move in place
substance 1 had weaker attraction; molecules now move around each other
substance 1 had stronger attraction; molecules now move in place

JT has a substance moving in place in a closed container. What happens if he transfers heat into the closed container?
molecules move faster and the substance would be a liquid
molecules move slower and the substance would be a liquid
molecules move slower and the substance would be a solid
molecules move faster and the substance would be a solid

If the same amount of thermal energy is added to these ice samples, which will melt first and why?
Ice sample 3 because with more mass, kinetic energy will rise faster
Ice sample 1 because with less mass, kinetic energy will rise faster

Lulu heated up 3 identical containers on a stove and recorded their increase in temperature. What explains the results?
More energy was added to the 400 g sample because it had more mass
Energy was removed from the 400 g sample to give it a lower temperature
More energy was added to the 100 g sample so it increased more
The same energy was added to all & the increas was proportional to the mass

Ty had a container of a substance in the gas phase. He left it outside. Upon returning, it was a liquid. What happened?
molecules were moving in place then moving around each other
molecules were moving around each other then moving in place
molecules were moving around each other then moving away from each other
molecules were moving away from each other then moving around each other
