Complete each sentence to explain how increasing the volume of a gas at a constant temperature affects its pressure.

You can use each word once, more than once, or not at all:

When the volume of a gas is increased at a constant temperature, the gas particles have the same average _____________.

The particles now travel further between the walls of the container, resulting in a lower _____________ of collisions with the walls.

This produces a smaller average _____________ per unit area over the container walls, which results in a lower pressure.

A technician investigates how the pressure and volume of a sealed sample of air are related when kept at a stable room temperature. Their experimental measurements are recorded in the table below:

The technician proposes the hypothesis:

Use the data in the table to determine whether the technician's hypothesis is supported.

A robotic submersible is designed to explore the Mariana Trench. Explain why the water pressure acting on the exterior of the submersible increases significantly as it descends to greater depths.
