Latent Heat of Fusion | Physics Explained

AI Thread Summary
The discussion focuses on using the formula for latent heat of fusion to calculate the average latent heat from three cases. The user is unclear about how to apply the formula and what specific variables represent, such as the mass of water and specific heat capacities. They express confusion regarding the terms in the formula, particularly Cw, Ci, and the temperatures involved. A suggestion is made to use the formula correctly for each case, sum the values, and then divide by three to find the average. Clarification on these variables is essential for accurate calculations.

You say "I am not real sure exactly how to use it [the formula for latent heat of fusion] to find the average of some data." What exactly are you trying to find? Heat of fusion has nothing to do with "finding an average".
 
Well I just need to find the latent heat of all 3 of them, and then just average them all together. I thought I plugged everything in right, but when I tried to submit my answer it said that it was wrong. I just need to know where to plug everything in at.
Thanks
 
Or maybe, another website I could go to that would help me with this. I have tried some, but they didn't work for me.
Thanks
 
Okay, so you really have two problems: first use "Mw*Cw*(Tw-T) = Mi*Ci*(T-Ti)+L*Mi" to find the Latent Head of Fusion in each of the three cases, then add those values and divide by 3.
 
Well i guess my real problem is what is the mass of water. I know the volume (4 cups). I don't know what Cw is. I think Tw is temp of water. I think T is the final Temperater. Mi is I assume Mass of the ice. Not sure what Ci is. Again I believe that Tis the final Temperature and Ti is the temp of the ice. L is the Latent heat and Mi is the mass of ice again. Is that correct?
 

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
