The reason for this observation is that at, , (a) pressure increases, , (b) temperat m4, (©) pressure decreases (b) temperature decreases, , (d) temperature increases, js. (c) Pressure at the top of a mountain (or at high altitude] is low. This suggests that boiling, takes place at lower temperature, due to which things take more time to boil, , However, in a pressure cooker, pressure is increased and hence, boiling point, increases. Thus, things comes to boil in a pressure cooker in a less period of time., , 2 Which of the following property of water can be used to explain the, spherical shape of rain droplets?, (a) Viscosity (b) Surface tension, (c) Critical phenomena (d) Pressure, , ic he of rain droplets is due to surface tension. The lowest energy state, (6) The sonal habe li crept ium, Sara uno Wa caren, the surface area of the liquid to the minimum. The tain droplets are spherical because, , for a given volume, a sphere has minimum surface area,, , e (V) versus temperature (T) for a gas at constant pressure, ; $ bgt Oe through the origin.
