Please answer ALL of the questions 1.An inflated balloon is inside vacuum chamber at STP. We double the pressure on the balloon. Which statement matches the effects on the balloon?

It reduces in size by half.

It decreases to a quarter of the size.

Volume stays the same but the balloon feels less tight.

It doubles in volume.

2. A balloon contains 5.0 L of air at 80.0 kPa. You squeeze it to a volume of 0.75 L. What is the pressure of air inside the balloon?

560 kPa

533 kPa

203 kPa

410 kPa

3. Which description matches the graph above? (see picture below for this question)

When volume increases, pressure goes up and then down.

When volume increases, pressure decreases.

When volume increases, pressure increases.
