Water has a very high specific heat capacity when compared to most other common materials. In fact, ethyl alcohol has a specific heat that is only about that of water, whereas the specific heat of lead is about that of water. Suppose that you have equal‑mass samples of each material and that each sample is at the same initial temperature. You then carefully transfer the same amount of heat into each sample and measure the resulting final temperature of each. Rank the final temperature of each sample from highest to lowest.

Respuesta :

Answer:

Lead, Ethyl alcohol and water.

Explanation:

Specific heat capacity of a substance can be define as the quantity of heat that is absorbed by a substance needed to change the temperature of a unit mass of one kilogram of the substance by one kelvin

The ranking of the final temperature of the substances from highest to lowest is;

Lead > Ethyl alcohol > Water

We are told that water has a very high specific heat capacity.

Specific heat capacity of ethyl alcohol is 2.46 J/g.K which is about 2/5 of water

Specific heat capacity of lead = (1/30) of water

Now, the specific heat capacity is the heat required to raise the temperature of a substance.

This means that the higher the specific heat capacity, the lower the final temperature.

Now, from the samples given, we can say that;

  • Water has the highest specific heat capacity
  • Ethyl alcohol has the second highest specific heat capacity
  • Lead has the lowest specific heat capacity.

Thus, lead will have the highest final temperature followed by ethyl alcohol, then water.
