Question

on NO2
Consider the following two statements
a. If a gas container in motion is suddenly stopped, the temperature of the gas rises
b. A gas can be liquefied at any temperature by increase of pressure alone.
The correct statement(s) is/are
a only
bonly
NON
Both a and b
Neither a norb​

Answer 1

Answer:

Only option b is correct, because when we increase pressure on a liquid it's density starts to increase and reaches the threshold to be able to exist in its liquid state with or without increase in temperature.

Explanation:

(If we keep on cooling it down to keep the difference between its original temp and the temp after we start to pressurize it, take it like a 12th class student who can decrease the pressure on top of him by gaming.).

Answer 2

Only statement A is correct.

• When the gas container is in motion, then its molecules move in a random motion known as disordered motion but when it is suddenly stopped then its its temperature increases due to the conversion of kinetic energy of ordered motion into disordered motion.
• When a gas is liquefied at a particular temperature by just increasing the pressure of the gas then the temperature of the gas increases on its own and then the gas cannot be liquefied. But if the temperature is below or equal to the critical temperature, then it can be liquefied by increase of pressure alone.
