Charles's Law relates gas volume to which variable at constant pressure?
Answer: Absolute temperature
Charles's Law states gas volume is directly proportional to absolute temperature at constant pressure.
Why does the temperature inside a hyperbaric chamber rise during compression?
Answer: Compression of gas releases heat (adiabatic heating)
Compressing gas rapidly raises its temperature through adiabatic heating.
What temperature change occurs inside a chamber during decompression?
Answer: Temperature cools due to gas expansion
Expanding gas during decompression absorbs energy, cooling the chamber atmosphere.
The combined gas law incorporates the relationships among which three variables?
Answer: Pressure, volume, temperature
The combined gas law links pressure, volume, and temperature of a fixed gas mass.
Gay-Lussac's Law states that at constant volume, gas pressure is proportional to what?
Answer: Absolute temperature
Gay-Lussac's Law states pressure is directly proportional to absolute temperature at constant volume.
Why is fire risk a serious concern in hyperbaric environments?
Answer: Elevated oxygen partial pressure accelerates combustion
Higher oxygen partial pressure causes materials to ignite more easily and burn faster.
When using absolute temperature in gas law calculations, which scale is required?
Answer: Kelvin
Gas laws require absolute temperature, measured in Kelvin, to be accurate.
