Surface tension decreases with increase in .......

These questions consist two statements each, printed as Assertion and reason, while answering these question you are required to choose any one of the following four responsis: (a) If both the assertion and reason are true and reason is a true explanation of the assertion. (b) If both the assertion and reason are true but the reason is not the correct explanation of assertion. (c ) If the assertion is true but reason is false. (d) If both the assertion and reason are false. Q. Assertion: Surface tension decreases with increase in temperature. Reason: On increasing temperature kinetic energy increases and intermolecular forces decreases.

Surface tension is exhibited by liquids due to force of attraction between molecules of the liquid. The surface tension decreases with increase in temperature and vanishes at boiling point. Given that the latent heat of vaporation for water rho_(w) = 540kcal/kg ,mechanical equivalent heat =4.2j/cal Avogadro's No. N_A = 6.0 xx 10^26 , and the molecular weight of water M_A = 18 kg for 1 k mole. Estimate the energy required for oe molecule of water to evaporate.

Assertion : Surface tensian decreases with increase in temperature. Reason : On increasing temperature kinetio energy increases and intermolecular forces decreases.

Assertion : Surface tensian decreases with increase in temperature. Reason : On increasing temperature kinetio energy increases and intermolecular forces decreases.

Regarding the surface tension property of liquids, the correct statements is/are a) surface tension decreases with increase of temperature b) at 20^@ C the surface tension of ethanol is greater than that of water c) the dimensions of surface tension is SI units is Nm^(-1) d) in the fine polishing of the glass, the edges become smooth due to surface tension

Statement I: A small drop of mercury is spherical F bigger drops are oval in shape. Statement II: Surface tension of liquid decreases with increase in temperature.
