Question

. A student left a sealed jar of water outside her home. Water can be a solid, liquid, or gas. When she put it outside, the water was a solid. Twelve hours later, the water had changed phase and was a liquid. What happened to the water molecules?

Answer 1

when the water went from a solid to a liquid (ice to fluid) the water had gotten warmer, meaning that the molecules had started to move around faster breaking the hydrogen bonds to form the liquid.
