4. If a certain mass of mercury has a volume of 0.002 m3 at a temperature of 20 C, what will be the volume at 50 C? A. 0.004021624 m3 B. 0.002021624 m3 C. 0.000010812 m3 D. 0.002010812 m3
If a certain mass of mercury has a volume of 0.002 m3 at a temperature of 20°C, the volume at 50°C is 0.002010837 m^3. Density of mercury is 13545 kg/m^3 at 20 deg.C ; 13472 kg/m^3 at 50 deg, C ; M = (13545 kg/m^3)*(0.002 m^3) = 27.09 kg ; Let V m^3 = volume at 50 deg. C ; (13472 kg/m^3)*(V m^3) = 27.09 kg ; V = 27.09/13472 = 0.002010837 m^3.

A block has a volume of 0.07 m3 and a density of 3500 kg/m3. The force of gravity acting on the block in air is 2401 N. density = mass / volume , mass= 3500*0.07 =245 kg , force = mass *acc , force = 245 *9.8 = 2401 N.
