Calculating Latent Heat of Ice: A Physics Practical Guide

In summary, the conversation discusses the equation for manipulating the results of a physics practical involving the transfer of energy between water and ice. It involves the specific heat capacity and change in temperature of water and ice, as well as the latent heat of fusion. The conversation clarifies the role of the different variables and the concept of common temperature.

Homework Statement



Hi, I've been given the following information to manipulate the results of my last physics practical:

Mass Of Water * Specific Heat Capacity of Water * Change in Temperature of Water = Latent Heat of Ice * Mass of Ice + Mass of Ice * Specific Heat Capacity of Water * Change in Temperature of Water.

Homework Equations





The Attempt at a Solution



Now, the left hand side is the energy lost by water to ice, then L(Ice)*M(Ice) is the total heat absorbed by ice but what is Mass of Ice * Specific Heat Capacity of Water * Change in Temperature of Water?

When ice melts by absorbing the required latent heat of fusion from its surroundings, it transitions from ice at zero C to water at zero C. If the water bath it's melting into is not at zero C also, then both are going to change until they reach a common temperature. Hence, two different "Change of Temperature of Water"s.

Related to Calculating Latent Heat of Ice: A Physics Practical Guide

1. What is latent heat of ice?

The latent heat of ice is the amount of energy required to change one unit of mass of ice from a solid state to a liquid state, without changing its temperature. It is also known as the heat of fusion.

2. Why is it important to find the latent heat of ice?

Finding the latent heat of ice is important in many scientific and practical applications. It helps us understand the behavior of water and ice, and also plays a crucial role in fields such as refrigeration, climate science, and materials science.

3. How is the latent heat of ice measured?

The latent heat of ice can be measured using a calorimeter, which is a device that measures the heat absorbed or released during a phase change. The process involves adding a known amount of heat to a sample of ice and measuring the resulting change in temperature.

4. Does the latent heat of ice change with temperature?

No, the latent heat of ice remains constant at a given pressure and does not change with temperature. However, as the temperature of the ice increases, the amount of heat required for a phase change also increases.

5. Can the latent heat of ice be calculated?

Yes, the latent heat of ice can be calculated using the formula Q = mL, where Q is the heat added or removed, m is the mass of the sample, and L is the latent heat of ice. This calculation assumes that the ice is at its melting point and that the entire sample undergoes a phase change.
