Question

when something is melting do the molecules move faster or slower? and is melting a physical or chemical property?

Answer 1

when something is melting the molecules are gradually beginning to move more and faster, melting is a physical property

Answer 2

yes because the attraction force between the atom become weak..
that explain why we cannot change the solid's shape easier...(need large force)
it was physical proverty because the composition of molekule is still same


4 example:
ice and water
still H2O
ice(solid) turn to water(liquid)=H2O
