Initial Temp Homework: Copper in Water, Aluminum Cup

Click For Summary
SUMMARY

The discussion focuses on a thermal equilibrium problem involving a 0.150 kg mass of heated copper, a 0.375 kg aluminum calorimeter cup, and 0.200 kg of water, all initially at 25°C and reaching equilibrium at 28°C. The key equations utilized are the specific heat formula Q=cm(delta)T and the principle of conservation of energy, which states that the heat lost by the copper equals the heat gained by the calorimeter and water. The student is tasked with determining the initial temperature of the copper shot using these principles.

PREREQUISITES
  • Understanding of specific heat capacity and its formula Q=cm(delta)T
  • Knowledge of thermal equilibrium concepts
  • Familiarity with mass and temperature units in physics
  • Basic algebra skills for solving equations
NEXT STEPS
  • Study the specific heat capacities of copper, aluminum, and water
  • Learn how to apply the conservation of energy principle in thermal systems
  • Practice solving thermal equilibrium problems with varying masses and temperatures
  • Explore advanced topics in thermodynamics, such as heat transfer mechanisms
USEFUL FOR

Students in physics or engineering courses, educators teaching thermodynamics, and anyone interested in understanding heat transfer and thermal equilibrium concepts.

Homework Statement


A student doing an experiment pours 0.150 kg of heated copper **** into a 0.375 kg aluminum calorimeter cup containing 0.200 kg of water. The cup and water are both initially at 25 C. The mixture (and the cup) comes to thermal equilibrium at 28 C. What was the initial temperature of the shot?


Homework Equations


The only equations in the chapter are specific heat:

Q=cm(delta)T or c=Q/m(delta)T
