A golf ball has more mass than a tennis ball because it ____.
1 answer:
Answer:
b. contains more matter.
A golf ball has more mass than a tennis ball because<u> it contains more matter</u> .
Explanation:
Volume = Total space enclosed enclosed by a substance or quantity of 3-D space occupied by solid, liquid or gas.It is measures in or L.
<u>Mass = Total matter (content)</u><u> present in a given substance</u><u> . It is measured in Kg</u>.
Density = It is defined as mass per unit volume of a substance .
The density of golf ball is more because it has more mass or more matter (content)than that of tennis ball.

According to Graham's Law ," the rates of effusion or diffusion of two gases are inversely proportional to the square root of their molecular masses at given pressure and temperature".
r₁ / r₂ =
---- (1)
r₁ = Rate of effusion of He
r₂ = Rate of Effusion of O₃
M₁ = Molecular Mass of He = 4 g/mol
M₂ = Molecular Mass of O₃ = 48 g/mol
Putting values in eq. 1,
r₁ / r₂ =
r₁ / r₂ =
r₁ / r₂ = 3.46
Result:
Therefore, Helium will effuse 3.46 times more faster than Ozone.
