Read the following statements and choose the correct option :
Assertion (A) :On applying pressure, gas can be compressed easily.
Reason (R) :When we apply pressure to a gas, the intermolecular space between gaseous particles decreases and it gets compressed.
Correct Answer :
Both (A) and (R) are true and (R) is the correct explanation of (A).
Solution :
The correct answer is Both (A) and (R) are true and (R) is the correct explanation of (A).
Analysis of Assertion (A):
Gases are characterized by having large intermolecular spaces between their particles and weak intermolecular forces. Because of these large gaps between particles, applying external pressure pushes the particles closer together, allowing gases to be compressed very easily compared to liquids and solids. Therefore, Assertion (A) is true.
Analysis of Reason (R):
When pressure is applied to a gas contained in a vessel, the force exerted reduces the empty distance (intermolecular space) existing between the gas molecules. As the intermolecular distance decreases, the volume of the gas reduces, causing it to compress. Therefore, Reason (R) is true and accurately explains why Assertion (A) occurs.
Since both statements are factually correct and Reason (R) provides the exact scientific cause for Assertion (A), the correct option is that both (A) and (R) are true and (R) is the correct explanation of (A).
