Effect of TIME on SPECIFIC HEAT?

Click For Summary
SUMMARY

The forum discussion centers on an experiment conducted using a calorimeter to determine the specific heat of an unknown metal by measuring temperature changes in water. The experiment involved recording the initial temperatures of both the metal and water, as well as the final equilibrium temperature. Additionally, the time taken to reach equilibrium was measured, highlighting its significance in understanding heat transfer dynamics. The participants suggested plotting temperature variation against time to visualize the cooling process and analyze the data effectively.

PREREQUISITES
  • Understanding of calorimetry principles
  • Knowledge of specific heat capacity calculations
  • Familiarity with temperature measurement techniques
  • Basic graphing skills for data visualization
NEXT STEPS

We did an experiment using a calorimeter in class, where we dropped a hot piece of metal into water in the calorimeter. We measured initial temp of metal + water, and the final equilibrium temperature. This allowed us to calculated the specific heat of the unknown metal (we also had the mass etc).


However, we also were asked to measure the TIME taken to reach equilibrium after the metal was added to the water, but why? What significance does the time to reach equilibrium have?

Thanks!

What graphs should I draw?

We did an experiment using a calorimeter in class, where we dropped a hot piece of metal into water in the calorimeter.

What graphs should I plot though? We were told to plot graphs but I've got no idea what to plot.

Thanks!
 


you may plot temperature variation with time!
