If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

Vedclass · Answer

(A) When a bottle of cold carbonated drink is opened,the high-pressure gas inside the bottle expands rapidly into the atmosphere. This rapid expansion is an adiabatic process because it happens so quickly that there is no time for heat exchange with the surroundings. According to the first law of thermodynamics,for an adiabatic expansion $(dQ = 0)$,the work done by the gas $(dW > 0)$ results in a decrease in internal energy $(dU Due to this sudden cooling,the water vapour present in the air near the opening condenses into tiny liquid droplets,forming a visible fog.

$Assertion:$ 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 condensation of water vapours.

The pressure and density of a diatomic gas $\left(\gamma=\frac{7}{5}\right)$ changes adiabatically from $(P, d)$ to $(P^{\prime}, d^{\prime})$. If $\frac{d^{\prime}}{d}=32$, then $\frac{P^{\prime}}{P}$ is:

The temperature of a hypothetical gas increases to $\sqrt{2}$ times when compressed adiabatically to half the volume. Its equation can be written as

An ideal gas in a cylinder is compressed adiabatically to one-third of its original volume. $A$ work of $45 \,J$ is done on the gas by the process. The change in internal energy of the gas and the heat flowed into the gas, respectively are

For an adiabatic expansion of a perfect gas,the value of $\frac{\Delta P}{P}$ is equal to

At $27^\circ C$,a gas is suddenly compressed such that its pressure becomes $1/8$th of the original pressure. The temperature of the gas will be $(\gamma = 5/3)$.
