Calculating Unfrozen Water After Heat Transfer

AI Thread Summary
To determine how much water remains unfrozen after 50.2 kJ is transferred from 260g of liquid water at its freezing point, relevant equations include Q = mc(Tf - Ti) and Q = ±mL. The discussion emphasizes the need to calculate the mass of water that remains in liquid form after heat transfer. Participants suggest that the problem involves both sensible heating and latent heat calculations. A clear understanding of the phase change from ice to water is crucial for solving the problem. The focus remains on applying these equations effectively to find the mass of unfrozen water.

What equations do you think you will need here? Sensible heating maybe?

You need to show some attempt before anyone at PF can help you.
 
k may b these equations

Q =mc(Tf - Ti)
Q =+/-mL
 
Pinkythermo said:
Q =+/-mL

So how much mass is converted from ice to water?
