Chapter 15: Problem 1

When a bottle of soda water is opened, the partial pressure of \(\mathrm{CO}_{2}\). (a) decreases (b) increases (c) remains the same (d) none of these

Short Answer

Expert verified
(a) decreases

Step by step solution

01

Understanding Change in Pressure

When a bottle of soda is closed, the carbon dioxide is pressurized. This means there is a high pressure inside the bottle because of the CO2 gas trapped inside.
02

Understanding the Effect of Opening the Bottle

On opening the bottle, the \(\mathrm{CO}_{2}\) is allowed to escape, thereby reducing the amount of \(\mathrm{CO}_{2}\) present inside the bottle.
03

Consequence on the Partial Pressure of CO2

Since the amount of \(\mathrm{CO}_{2}\) inside the bottle reduces when the bottle is opened, the partial pressure of the \(\mathrm{CO}_{2}\) inside the bottle decreases.
