Answer:
V₂ = 46.34 mL
Explanation:
Given data:
Initial temperature = 273 K
Initial volume = 50.0 mL
Final temperature = 253 K
Final volume = ?
Solution:
The given problem will be solve through the Charles Law.
Charles Law
"The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure"
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
by putting values in formula,
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 50.0 mL × 253 K / 273 k
V₂ = 12650 mL.K / 273 K
V₂ = 46.34mL

The object with more volume is the inflated balloon
Explanation:
Volume is about how much space an object or material occupies; in this context, if the inflated balloon has the double size of the bag of marbles then the balloon has more volume because this is occupying more space.
Moreover, the volume should not be confused with other factors such as mass or weight because it is likely the marbles weight more but this does not imply the marbles have more volume. Also, the balloon contains gas and gases tend to expand and occupy more space, which does not occur with solids such as marbles because these have a defined volume.
