In an adiabatic process, the temperature of a gas decreases. What happens to its pressure? (2021)
Step 1: Understand what an adiabatic process is. It means that no heat is exchanged with the surroundings.
Step 2: Know that in an adiabatic process, if the temperature of a gas decreases, it means the gas is losing energy.
Step 3: Recall the ideal gas law, which states that pressure (P), volume (V), and temperature (T) are related: PV = nRT, where n is the number of moles and R is the gas constant.
Step 4: If the temperature (T) decreases and the volume (V) remains constant, the pressure (P) must also decrease to keep the equation balanced.
Step 5: Therefore, in an adiabatic process, when the temperature of the gas decreases, the pressure also decreases.
