Question

If ice and water both have the same temperature of 0°C, the kinetic energy of water

molecules is

i) high in both water and ice

ii) low in both water and ice

iii) lower in water than ice

iv) higher in water than ice

Answer 1

I guess as KE=1/2(mv^2)
As density of ice is more mass will be more for same volume of both ice and water .as mass is more KE is more for ice
But in ice as molecules are compactly packed so velocity of atoms will be lower than loosely packed water molecules
And as in formulae there is square to the velocity so its considerable that KINETIC ENERGY CAN BE MORE IN WATER THAN IN ICE

Just tried .verify with teacher she will clarify if u explain this concept to her
Add me thanks pls
