Homework Help: Thermal Energy Question

Click For Summary
SUMMARY

The discussion centers on the principles of thermal energy transfer, specifically the conservation of energy between a spoon and water. The spoon loses thermal energy as it cools down, while the water gains thermal energy as it warms up. Participants emphasize the importance of applying the conservation of energy principle to solve the problem effectively.

PREREQUISITES
  • Understanding of thermal energy transfer
  • Familiarity with the concept of conservation of energy
  • Basic knowledge of heat exchange processes
  • Ability to apply mathematical equations related to energy
NEXT STEPS
  • Research the laws of thermodynamics
  • Learn about specific heat capacity and its calculations
  • Explore practical examples of heat transfer in everyday scenarios
  • Study energy conservation equations in physics
USEFUL FOR

Students studying physics, educators teaching thermal dynamics, and anyone interested in understanding energy transfer in physical systems.

Homework Statement
A 150g steel spoon (constant = 420J/kg degrees Celsius) initially at 19 degrees Celsius is placed into a 250mL cup of water at 89 degrees Celsius. When both objects reach the same temperature what temperature will that be?
Relevant Equations
change in energy = (mass)(constant)(change in temperature)
water constant = 4200J (kg degrees Celsius)
I don't know what to do!

The spoon will cool down and lose energy, the water will warm up and gain energy. Use conservation of energy.
