Specific Latent Heat of Ice HELP

In summary, the conversation discusses determining specific heat and latent heat without using calorimeters. The use of specific heat and latent heat are clarified and it is mentioned that they can be found by measuring vapor pressures and determining enthalpies of vaporization for both solid and liquid phases at 0 degrees Celsius.

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.
 

1. What is the specific latent heat of ice?

The specific latent heat of ice refers to the amount of energy required to change one kilogram of ice at 0°C into water at 0°C, without changing its temperature.

2. How is the specific latent heat of ice measured?

The specific latent heat of ice is typically measured using a calorimeter, which is a device that measures the amount of heat absorbed or released during a phase change. The ice is placed in the calorimeter and the amount of heat required to melt the ice is measured.

3. What is the value of the specific latent heat of ice?

The specific latent heat of ice is approximately 334 kJ/kg at a pressure of 1 atmosphere. However, this value may vary slightly depending on the temperature and pressure at which it is measured.

4. How does the specific latent heat of ice affect the melting and freezing of ice?

The specific latent heat of ice plays a crucial role in the melting and freezing of ice. When heat is added to ice, it absorbs the energy and uses it to break the bonds between the water molecules, allowing the ice to melt. Similarly, when heat is removed from water at 0°C, it uses the energy to form bonds between the molecules and freeze into ice.

5. What are the real-life applications of the specific latent heat of ice?

The specific latent heat of ice is important in many practical applications, such as refrigeration and air conditioning systems. It is also used in industries that require precise temperature control, such as food and beverage production. Additionally, the specific latent heat of ice is crucial in understanding and predicting weather patterns, as the melting and freezing of ice plays a significant role in the Earth's climate.
