Heat and Mass: Raising Ice and Water Temperatures

Click For Summary
SUMMARY

The discussion centers on the thermal energy required to raise the temperature of 5 grams of ice versus 5 grams of water by 6 degrees Celsius. It is established that ice has a specific heat capacity that is half that of water, leading to the conclusion that it takes more thermal energy to raise the temperature of ice. The equation Q=mcΔt is utilized to analyze the energy requirements, confirming that the energy needed for ice includes both the energy to melt it and the energy to raise its temperature, while water only requires energy for temperature increase.

PREREQUISITES
  • Understanding of specific heat capacity
  • Familiarity with the equation Q=mcΔt
  • Knowledge of phase changes, specifically melting
  • Basic thermodynamics concepts
NEXT STEPS
  • Study the concept of specific heat capacity in detail
  • Learn about phase transitions and their energy requirements
  • Explore practical applications of Q=mcΔt in real-world scenarios
  • Investigate the thermal properties of different substances
USEFUL FOR

Students in physics or chemistry, educators teaching thermodynamics, and anyone interested in understanding heat transfer and energy calculations in phase changes.

Homework Statement



Given that ice has a specific heat that is half of that of water, does it take more thermal energy to raise the temperature of 5 grams of water or 5 grams of ice by 6 degrees Celsius?

Homework Equations



Q=mc delta t


The Attempt at a Solution



So I think it takes more energy to raise the temperature of water. Am I right? The answer given is ice, could that just be a mistake?

If you assume the temperature of the ice is zero degree, the ice takes more energy to melt and then rise the temperature. Where as the water directly rises the temperature.
