Certified Hyperbaric Technologist Test Hyperbaric Physics Fundamentals 4

Question 1

Charles's Law relates gas volume to which variable at constant pressure?

Accepted Answer

Absolute temperature

Answer

Charles's Law states gas volume is directly proportional to absolute temperature at constant pressure.

Question 2

Why does the temperature inside a hyperbaric chamber rise during compression?

Accepted Answer

Compression of gas releases heat (adiabatic heating)

Answer

Compressing gas rapidly raises its temperature through adiabatic heating.

Question 3

What temperature change occurs inside a chamber during decompression?

Accepted Answer

Temperature cools due to gas expansion

Answer

Expanding gas during decompression absorbs energy, cooling the chamber atmosphere.

Question 4

The combined gas law incorporates the relationships among which three variables?

Accepted Answer

Pressure, volume, temperature

Answer

The combined gas law links pressure, volume, and temperature of a fixed gas mass.

Question 5

Gay-Lussac's Law states that at constant volume, gas pressure is proportional to what?

Accepted Answer

Absolute temperature

Answer

Gay-Lussac's Law states pressure is directly proportional to absolute temperature at constant volume.
