Specific Latent Heat of Ice HELP

AI Thread Summary
To determine the specific latent heat of ice in J/kg without a calorimeter, one must measure the vapor pressures of both the solid and liquid phases and calculate the enthalpies of vaporization at 0°C. The difference between these enthalpies will yield the enthalpy of fusion. While specific heat and latent heat are distinct concepts, the term "specific latent heat" is not commonly used but is not incorrect. Essential equipment includes a mass scale, heater, thermometer, and stopwatch. Accurate measurements and calculations are crucial for determining the latent heat effectively.

How do i determine this, in J/kg, without the use of any calorimeteres? Keep it simple please

Thanks :biggrin:

You can always just google it.

I don't think you can "determine" it without using a calorimeter.
 
Specific heat and latent heat are two different things. Are you supposed to find both of them?

Edit: just noticed that the unit, J/kg, is for latent heat. "Specific heat" and "heat capacity" are both equivalent shorter phreases for "specific heat capacity." I have never heard the use of the term "Specific Latent heat" but I'll not go out on a limb and say it's "wrong." It sure sounds funny though.

No matter how you find them, even without a calorimeter, you need mass-scale, a heater, a thermometer, and a stopwatch.

Measure vapor pressures of the solid and liquid phases; determine enthalpies of vaporization for both phases at 0 C; difference is enthalpy of fusion.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
