A 37.2-g sample of lead (Pb) pellets at 20°C is mixed with a 62.7-g sample of lead pellets at the same temperature. What are the final mass, temperature, and density of the combined sample? The density of Pb at 200C is 11.35 g/cm^3.

Answer:

Mass of sample is 99.9 g, density of ample is 11.35 [tex]g/cm^{3}[/tex] and temperature of sample is [tex]20^{0}\textrm{C}[/tex]

Explanation:

Mass is an additive property. Therefore mass of combined sample is summation of masses of two pellets.

Mass of combined sample = (37.2+62.7) g = 99.9 g

Density is an intensive property. Therefore density of combined sample of lead will be same as with density of Pb.

Density of combined sample = 11.35 [tex]g/cm^{3}[/tex]

Temperature is an intensive property. Therefore temperature of combined sample of lead will be same as with individual pellets.

temperature of combined sample = [tex]20^{0}\textrm{C}[/tex]
