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.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

lol for the pointsss
