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.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
