A new liquid substance has been discovered that freezes at 45 degrees celsius and has a latent heat of 462,000 J/kg when freezing. a scientist poured the liquid (which was at 45 celsius) into a 9 degrees celsius cup (Ccup = 864 J/kg*K) which caused some, but not all, of the liquid to freeze. as a result, the liquid lost 86,000 J of ehat until thermal equilibrium was reached. determine how much of the liquid froze and the cup's mass.
