Calorimetry(determination of specific heat capacity)

AI Thread Summary
Determining the specific heat capacity of a sample can be achieved by cooling it to the temperature of ice, as both the heat of fusion and heat of vaporization are relevant in calorimetry. However, cooling to ice temperature may complicate calculations due to the phase change involved in melting ice. The change in temperature for the sample is calculated as the initial temperature minus the final temperature, which is the temperature of the ice. This method requires careful consideration of the heat transfer processes involved. Overall, while cooling to ice temperature is feasible, it introduces additional complexities compared to heating to boiling point.

can we determine a specific heat of a sample by cooling it to the temperature of ice rather than heating it to the boiling point of water?

why not?we have the"heat of vaporization" but we have the"heat of fusion",too

then, how to calculate the change of temperature of the sample?
is it 0°C minus the final temperature?
 
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...
