PHYSICS HOMEWORK HELP PLEASE?
The water molecule is polarized. Explain what this statement means and what it has to do with why it takes so much energy to change a block of ice to a gas.

Water is a polar molecule, allowing for the formation of hydrogen bonds.
It takes a lot of heat to increase the temperature of liquid water because some of the heat must be used to break hydrogen bonds between the molecules. In other words, water has a high specific heat capacity.
Just as it takes a lot of heat to increase the temperature of liquid water, it also takes an unusual amount of heat to vaporize a given amount of water, because hydrogen bonds must be broken in order for the molecules to fly off as gas. That is, water has a high heat of vaporization.
