Question

PLEASE HELP ME!!!!!

The tires on Adrian's classic corvette tires are at 120kPa and 27L of air after going to California. Before he started, the tires had 20L of air. Choose the correct statement.

Question 6 options:

The original pressure must be more than 120kPa because when P increases, V decreases.


The original pressure must be less than 120kPa because when P increases, V decreases.


The original pressure must be more than 120kPa because when P increases, V increases.


The original pressure must be less than 120kPa because when P increases, V increases

Answer 1

the second one is correct im pretty sure

Answer 2

According to Boyle's law:

Pressure of given mass of ideal gas is inversely proportional to its volume at a constant temperature.

That can be represented as:

PV=Constant

Where P represents pressure, V represents volume.

Here as the volume increases that is from 20 L to 27 L, So pressure must decreases, so the original pressure must be greater than 120 kPa.

So the answer is "The original pressure must be more than 120kPa because when P increases, V decreases".
