Assertion: When a bottle of cold carbonated drink is opened, a slight fog forms around the opening.
Reason: Adiabatic expansion of the gas causes lowering of temperature and condersation of water vapours.

A

If both assertion and reason are true and the reason is correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true, but the reason is false.

D

If assertion is false but the reason is true

Text Solution

Verified by Experts

The correct Answer is:
A
When a bottle of cold carbonate drink is opened. Then adiabatic expansion of gas evolved is done. Due to this temperature of gas decreases. It condenses the water vapour, which forms a slight fog around the opening.

When a bottle of cold drink is opened, the gas comes out with a fizzle due to:

Assertion: When temperature of cold junction of a thermocouple is lowered, the value of neutral temperature of this thermo couple is raised. Reason: When the difference of temperature of two junction is raised. More thermo emf is produced.

Assertion:- During adiabatic expansion of an ideal gas, temperature falls but entropy remains constant. Reason:- During adiabatic expansion, work is done by the gas using a part of internal energy and no heat exchange teakes place the system and the surrounding.

Assertion : When temperature of cold junction of a thermocouple is lowered, the value of neutral temperature of this thermocouple is raised. Reason : When the difference of temperature of two junction is raised, more thermo e.m.f. is produced.

Assertion (A): When hydrogen gas at high pressure and room temperature expands adiabatically into a region of low pressure, there is a decrease in temperature. Reason (R ) : Hydrogen gas at room temperature is above its inversion temperature.

Assertion : During an adiabatic process, heat energy is not exchanged between system and its surroundings. Reason : The temperature of a gas increases when it undergoes andn adiabatic expansion.

Assertion : A room can be cooled by opening the door of a refrigerator in a closed room. Reason : Heat flows from lower temperature (refrigerator) to higher temperature (room).
