Explain why the gas in the plastic bags is called 'cooking gas' and not LPG. 2. Is it possible to carry cooking gas in liquefied form in plastic bags? 3. Define the boiling point of a liquid and expla

I. LPG stands for Liquefied Petroleum Gas. The gas shown in the plastic bags is in its gaseous state, not liquefied. Therefore, calling it 'cooking gas' is more accurate in this context.

II. No, it is not possible to carry cooking gas in liquefied form in these plastic bags. Liquefied cooking gas (LPG) is stored under high pressure. Plastic bags are not designed to withstand such high pressure and would burst, posing a significant safety risk.

Q7. The boiling point of a liquid is the temperature at which its vapor pressure equals the external pressure. Since the external pressure (atmospheric pressure) affects the temperature at which a liquid boils, it must be specified for a standard definition. If the pressure is less than atmospheric pressure, water will boil at a lower temperature because less vapor pressure is required to overcome the reduced external pressure.
