Effect of TIME on SPECIFIC HEAT?

In summary, in the experiment using a calorimeter, we dropped a hot piece of metal into water and measured the initial and final equilibrium temperatures. This allowed us to calculate the specific heat of the unknown metal. We also measured the time taken to reach equilibrium, which can be plotted on a graph as temperature variation over time.

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?

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!
 

Related to Effect of TIME on SPECIFIC HEAT?

1. How does time affect the specific heat of a substance?

The longer a substance is exposed to a change in temperature, the more time it has to absorb or release heat energy. This results in a change in the specific heat of the substance, as it takes more energy to change the temperature of the substance over a longer period of time.

2. Is the effect of time on specific heat consistent for all substances?

No, the effect of time on specific heat can vary depending on the substance. Some substances may have a higher specific heat and therefore require more time to absorb or release heat energy, while others may have a lower specific heat and require less time.

3. How does the specific heat of a substance change over time?

The specific heat of a substance can change over time as it is exposed to different temperatures. As the substance absorbs or releases heat energy, its specific heat may increase or decrease accordingly.

4. Does the specific heat of a substance change at a constant rate over time?

No, the specific heat of a substance does not change at a constant rate over time. It may change at a faster rate initially, and then slow down as the substance reaches equilibrium with its surrounding temperature.

5. Can the effect of time on specific heat be manipulated or controlled?

Yes, the effect of time on specific heat can be manipulated or controlled through various means such as changing the temperature of the substance, adjusting the duration of exposure to heat, or altering the conditions in which the substance is being heated or cooled.
