Adiabatic Process – JEE Questions
Q1. During an adiabatic process, the pressure of a gas is found to be proportional to the cube of its absolute temperature. The ratio CP/CV for the gas is
- 4/3
- 2
- 5/3
- 3/2
Solution:
Option (4) 3/2 is correct
In an adiabatic process
Tγ = kP(γ-1)
T(γ/γ-1) = kP
Given T3 = kP
hence γ/γ-1 = 3;
3γ-3 = γ
γ = 3/2
CP/CV = 3/2
Q2. During an adiabatic compression of gas, its temperature
- Falls
- Rises
- Remains Constant
- Becomes Zero
Solution:
Option (2) Rises is correct
During adiabatic compression of gas, volume decreases hence pressure increases and as a result temperature of gas increases.
Adiabatic Process
Adiabatic Process is a thermodynamic process in which there is no heat exchange between the system and the environment. It means the energy of the system remains unchanged with time. For Example, the water inside a thermo steel bottle that remains hot is one of the best real-life examples of the Adiabatic Process.
In this article, we will learn what the is Adiabatic Process, its definition, example, and equation to explain the process and its graphical representation. We will also solve some numerical based on the adiabatic process and see the previous year’s questions of competitive exams.
