Explanation:
The pressure is constant, so, to calculate the volume, we can use Charles' Law:
\dfrac{V_{1}}{T_{1}} = \dfrac{V_{2}}{T_{2}}
Data:
V₁ = ?; T₁ = 450 K
V₂ = 103.4 L; T₂ = 284.9 K

Answer : The number of marbles lined up across the circumference of the earth can be, marbles
Explanation :
First we have to calculate the diameter of tiny marble.
r = radius of marble = 0.25 mm
Now we have to calculate the number of marbles can be lined up across the circumference of the earth.
Given:
Circumference of the earth distance =
conversion used:
Number of marbles can be lined up = marbles
Thus, the number of marbles lined up across the circumference of the earth can be, marbles
