2. Relative humidity is an expression of the ratio of the actual vapour pressure of the atmosphere when saturated at the same temperature
3. A rise or fall in temperature with no change in vapour pressure will cause a drop or rise, respectively, in relative humidity

Sodium __________ has inverted solubility curve i.e. its solubility increases with the lowering of temperature.
A cam should be designed only using uniform rise and fall within half of the cam, the remaining is dwell period, and without any dwell period in between the rise -fall periods and rise and fall periods should be same. The maximum rise in follower is 30 mm. How much the follower will rise when the follower is 120 degrees from its initial position of a cam?

Many surfactants that form micelles have a solubility below their C.M.C. Thus at a certain temperature, known as the _________ point, the solubility increases dramatically since the micelles are quite soluble.
Read the passage carefully and select the best answer to each question out of the given four alternatives. The conclusion of World Trade Organizations 11thbiennial ministerial conference at Buenos Aires was worrisome. From an Indian standpoint, there was no loss asstatus quo continues in the most important issue: the right to continue the food security programme by using support prices. But the inability of the negotiators toreach even one substantive outcome suggests that WTOs efficacy is under question. As a 164-country multilateral organisation dedicated to crafting rules of tradethrough consensus, WTO represents the optimal bet for developing countries such as India. Strengthening WTO is in Indias best interest. Perhaps the biggest threat to WTOs efficacy today is the attitude of the US. The worlds largest economy appears to have lost faith in the organisation and hasbegun to undermine one of its most successful segments, the dispute redressal mechanism. This is significant as the US has been directly involved in nearly half ofall cases brought to WTO. Separately, large groups of countries decided to pursue negotiations on e-commerce, investment facilitation and removal of tradeobstacles for medium and small scale industries. By itself this should not weaken WTO. But it comes at a time when there is growing frustration with gridlock atWTO. India did well to defend its position on its food security programme. The envisaged reform package which will see a greater use of direct cash transfers tobeneficiaries will be in sync with what developed countries do. But its important for India to enhance its efforts to reinvigorate WTO. In this context, Indias plan toorganise a meeting of some countries early next year is a step in the right direction. WTO represents the best available platform to accommodate interests of adiverse set of nations. Therefore, India should be at the forefront of moves to fortify it. Which of the following is the most successful segments of the WTO mentioned in the passage?
