Kristine said that an ice cube gains heat when placed in a warm glass of water. eric said that a hot cup of tea loses heat to cold hands. who has made the correct statement with regard to heat transfer?

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

1. they vary with a higher number because boiling is way hotter than melting
