During the last lesson we did an experiment in which we put food color into a cup of hot, room temperature and cold water. The color in the hot water dissolved the fastest and in the cold water it was slowest Temperature means how hot something is. Molecules can be moving in different directions and different speed. Hot water moves the fastest and move around very quickly. Room temperature molecules are moving with medium speed but they are connected. Cold water molecules are moving slow and they are connected very tightly.
To sum it up, molecules in water have two hydrogen and one oxygen.
