Question: A gas is compressed adiabatically. Which of the following statements is true? (2023)

Options:

Correct Answer: Temperature increases

Exam Year: 2023

Solution:

In an adiabatic compression, the temperature of the gas increases due to work done on it.

A gas is compressed adiabatically. Which of the following statements is true? (2023)

Step 1: Understand what adiabatic means. It means that no heat is exchanged with the surroundings during the process.
Step 2: Recognize that when a gas is compressed, work is done on the gas.
Step 3: Know that in an adiabatic process, the work done on the gas increases its internal energy.
Step 4: Realize that an increase in internal energy leads to an increase in temperature.
Step 5: Conclude that during adiabatic compression, the temperature of the gas increases.

Adiabatic Process – An adiabatic process is one in which no heat is exchanged with the surroundings, leading to changes in temperature due to work done on or by the gas.
Work and Temperature Relationship – In adiabatic compression, work done on the gas increases its internal energy, resulting in a rise in temperature.
