What is the most likely evidence of an energy transformation taking place when a skater glides over ice?

Skating blades become cold as kinetic energy is transformed into thermal energy

Skating blades become cold as kinetic energy is transformed into gravitational energy

Small tracks of water are left on the ice as kinetic energy is transformed into thermal energy

Small tracks of water are left on the ice as kinetic energy is transformed into gravitational energy

Small tracks of water are left on the ice as kinetic energy is transformed into thermal energy

Explanation:

Here when we see the evidence of energy transformation then we can say that when skater glides over the surface of ice then due to friction between the skates and the ice surface it generates heat

Due to this heat few of the ice will melt down and it converts into water

So here the energy transformation is in following way

first kinetic energy of the skater will convert into frictional work done

this frictional work will generate heat

due to heat it will convert the ice into water

so correct answer will be

Small tracks of water are left on the ice as kinetic energy is transformed into thermal energy

Small tracks of water are left on the ice as kinetic energy is transformed into thermal energy
