Re: Physics help




"> An important thing to notice is that the temperature of the water does
not
change. All that happens is that the water is transformed into ice, and it
happens by giving off energy, and that energy is used to increase the
temperature of the ice. It is all that happens.

Energy released from water is mass of water multiplied by latent heat of
fusion

Rise in temperature of ice is available energy divided by specific heat of
ice divided by mass of ice
Thanks, John. I guess I have a tendancy to overthink the problem. Since the
water stayed the same temperature, just had a phase change, the ice must
have been only 1 or 2 degrees below C.
