Assertion: The m.pt. of ice is lowered on increasing the pressure, whereas m.pt. of solids other than ice is raised upon increasing pressure. Reason: Ice shows H-bonding and leads to three dimensional solid of more volume.A. If both assertion and reason are true and the reason is the correct explanation of the assertion.B. If both assertion and reason are true but reason is not the correct explanation of the assertion.C. If assertion is true but reason is false.D. If assertion is false but reason is true. |
Answer» Correct Answer - A Ice `hArr` Water `V_(s) gt V_(w)` Thus, forward reaction occurs on increasing pressure, i.e., more ice will melt or m.pt.is lowered. Solid `hArr` Liquid `V_(s) lt V_(L)` Thus, more solid will be formed on increasing pressure. |
