Question

Which of the following has more potential energy?
1 gram of ice at 0 C or 1 gram of water at 0 C ? Give the reason.

Answer 1

1 gram of ice


Why - Kinetic energy depends on velocity and movement ( 1/2 mv^2)


As kinetic energy increases potential energy decreases ( Conservation of mechanical energy)

Since water particles can move around more freely as they are in liquid compare to ice which is solid, WATER WILL HAVE MORE KINETIC ENERGY, LESS POTENTIAL ENERGY
ICE WILL HAVE LESS KINETIC ENERGY MORE POTENTIAL ENERGY

Answer 2

Answer:Ice has more potential energy

Explanation:Ice has more potential energy which is released during the change of state from solid to liquid.
