Which of the following statements is INCORRECT?
Compressed natural gas (CNG) is used as a fuel in vehicles these days.
The oxygen supplied to hospitals in cylinders is not a compressed gas.
The oxygen supplied to hospitals in cylinders is a compressed gas.
In the gaseous state, the particles move about randomly at a high speed.
The oxygen supplied to hospitals in cylinders is not a compressed gas.
Compressed Natural Gas (CNG) is natural gas compressed to high pressures for use as an eco-friendly vehicular fuel. Similarly, oxygen supplied to hospitals in high-pressure cylinders is compressed gas, allowing large volumes of oxygen to be stored safely in portable containers. Therefore, stating that hospital oxygen is not a compressed gas is scientifically incorrect.

Think of a sponge filled with air: when you press down hard on it, you compress a large bulky sponge into a small, compact space. In the same way, massive volumes of gaseous oxygen are compressed into a rigid steel cylinder so it can be easily transported to hospitals.
COMP: COmpressed Medical & Petroleum gases occupy small Places under high pressure.
P1тАЛV1тАЛ=P2тАЛV2тАЛ тАФ Boyle's Law governing gas compression
Gases have large intermolecular spaces and high compressibility. By applying high pressure at room temperature (or lower), gas molecules are forced close together, reducing the volume significantly. This physical principle allows gases like natural gas, liquefied petroleum gas (LPG), and medical oxygen to be stored efficiently in heavy-duty metal cylinders.
Gases possess high compressibility compared to solids and liquids.
CNG (Compressed Natural Gas) is widely used as a cleaner alternative fuel in vehicles.
Oxygen cylinders in hospitals contain highly compressed oxygen gas for medical treatments and emergencies.
Particles in the gaseous state have negligible intermolecular forces and move randomly at very high speeds.
High storage efficiency in small volumes
Easy transportability of medical and fuel gases
High pressure poses safety hazards if cylinders are mishandled or exposed to extreme heat
Medical oxygen support in hospitals and ambulances
CNG fuel systems in public transport and cars
LPG cooking gas cylinders in households
Option B claims that oxygen supplied to hospitals in cylinders is not a compressed gas
