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.
