If a gas expands suddenly then its:
- A
Pressure decreases
- B
Temperature decreases
- C
Pressure and temperature both decrease
- D
None of the above
When a gas expands suddenly, it undergoes an adiabatic process, meaning there is no exchange of heat with the surroundings. In an adiabatic expansion, the gas does work on its surroundings, causing both its pressure and temperature to decrease. Therefore, option c is correct.
This is true, but it's only part of the effect. In an adiabatic expansion, both pressure and temperature decrease.

When a gas expands suddenly, it undergoes an adiabatic process, meaning there is no exchange of heat with the surroundings. In an adiabatic expansion, the gas does work on its surroundings, causing both its pressure and temperature to decrease.
This is incorrect. In an adiabatic expansion, there are observable changes in pressure and temperature.
