If the solubilities of different components (in a liquid-liquid extraction system) increase with rise in temperature, then the temperature above which they dissolve completely is known as the critical solution temperature (CST or consolute temperature). If solubilities increase with decrease in temperature, then CST is the temperature below which they dissolve completely. If a binary system has no critical solution temperature, it implies that

Price elasticity coefficient Change in price Change in Total Revenue 1) Zero Increase Decrease Increase Decrease (2) Less than 1 Increase Decrease Decrease Increase (3) Equal to 1 Increase Decrease No change No change (4) More than 1 Increase Decrease Decrease Increase  
Consider the following statements about the Atmospheric pressure phenomenon and identify the correct ones. Atmospheric pressure is basically a force in any area pushed by any surface by the weight of the Earth's atmosphere.  The atmospheric pressure increases with an increase in the altitude for any region.  The earth's rotation affects the pressure of the atmosphere in various ways.
Which of the following statements is/are true/false? 1. By increasing the temperature and pressure, we can convert atmospheric gases into liquid state. 2. A hot dry day means that the atmospheric temperature is high and the air humidity is low. Both these factors lead to an increase in the rate of evaporation and thus a large amount of cold formation.
Engines are rated at specified conditions. Then which of the following statements are correct? 1. Power developed increases as local temperature increases. 2. Power developed increases as local temperature decreases 3. Power developed is not dependent on local temperature. 4. Power developed increases as local atmospheric pressure increases. 5. Power developed increases as local atmospheric pressure decreases.
Which of the following is/are consequence/s of deforestation? (a) Increase of atmospheric temperature (b) Increase in level of CO2 in atmosphere (c) Increase of ground water level (d) Increases chances of natural calamities such as flood and drought.
Consider the following statements.
1. SI unit of atmospheric pressure is Nm-2 or pascal and CGS unit is dyne/cm2.
2. The barometer is a device by which the atmospheric pressure is measured.
3. The standard atmospheric pressure is the pressure required of 76 cm of Hg column or 760 mm of Hg column, which is equivalent to 1 atm.
Which of the statements given above is/are correct?

Which of the following statements is/are true? A. If we decrease temperature and increase pressure, we can liquefy atmospheric gases. B. A hot dry day means the temperature of the atmosphere is high and the humidity of air is low, Both these factors increase the rate of evaporation and thus enormous cooling is produced.
If a given mass of gas occupies a volume of 10cc at 1 atmospheric pressure and temperature 100°C, what will be its volume at 4 atmospheric pressure, the temperature being the same?
