Ascientist adds heat to each of the following substances. which will probably absorb the most heat before its temperature changes significantly?
a. 50 g of solid copper
b. 50 g of solid iron
c. 50 g of liquid water
d. 50 g of sand

Option (C) is the correct answer.

Explanation:

Specific heat is defined as the amount of heat necessary to raise the temperature of substance by one degree Celsius.  

Mathematically,          

where      Q = heat

                m = mass of substance

                 c = specific heat

                = change in temperature  

Since mass is same for all the given substances. Therefore, more is the specific heat of a substance more frequently it will raise the temperature.

Thus, we can see that specific heat of liquid water is highest out of the given options.

Hence, we can conclude that liquid water absorb most heat before its temperature changes significantly.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
