Calculating Latent Heat of Ice: A Physics Practical Guide

Click For Summary
SUMMARY

The discussion focuses on calculating the latent heat of ice using the equation: 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. The key takeaway is understanding that the left side represents the energy lost by water to ice, while the right side accounts for the heat absorbed by the ice and the heat associated with the temperature change of the water. The melting process involves two distinct temperature changes, emphasizing the need to consider the temperatures of both the ice and the surrounding water.

PREREQUISITES
  • Understanding of latent heat and phase changes in thermodynamics.
  • Familiarity with specific heat capacity and its calculation.
  • Knowledge of basic algebra for manipulating equations.
  • Concept of thermal equilibrium and temperature change.
NEXT STEPS
  • Study the concept of latent heat of fusion in detail.
  • Learn how to calculate specific heat capacity for different materials.
  • Explore thermal equilibrium and its implications in heat transfer.
  • Practice solving problems involving phase changes and energy transfer in thermodynamics.
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in thermodynamics, particularly those studying heat transfer and phase changes in materials.

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?
 
Physics news on Phys.org
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.
 
Hi Gneill!
