Assertion : Liquid \(\mathrm{NH}_{3}\) is used for refrigeration. Reason : Liquid \(\mathrm{NH}_{3}\) does not vapourise quickly.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
The liquid ammonia is colourless and boils at \(-33^{\circ} \mathrm{C}\). It freezes at \(-78^{\circ} \mathrm{C}\). Liquid ammonia has a larger heat of vapourization (327 \(\mathrm{cal} / \mathrm{g}\).). It is, therefore, used in ice-plants. So option (1) is correct.
