11.	Describe the global distribution of temperature with its characteristics.
Answer» The isotherms in the southern hemisphere are fairly parallel to the latitudinal lines. From South Pole to the Tropic of Capricorn the distance between these lines is almost equal. As the proportion of land in the southern hemisphere is limited, temperatures in these parts are largely influenced by latitude. In the northern hemisphere, the distance between these lines varies. In this hemisphere, the proportion of land is comparatively greater. This affects the distribution of temperature. These effects are seen in the form of variations in the distance between the isotherms and curved nature of these lines.

13.	Give reason:In the coastal areas, as compared to continental areas, the temperature of air is lower during the day but warmer at night.
Answer» There is difference in the heating and cooling of land and water. The air over the land gets heated faster and also cools rapidly. The air over the water gets heated slowly and also loses the heat in a slower manner. The temperature of air is lower during the day but warmer at night, in the coastal areas when compared to continental areas.

38.	If markings on thermometer are wiped out, how do we create new markings?
Answer» 1. Take some ice in a beaker. Immerse a thermometer in ice for two minutes. Mark the Mercury level. Now let the ice melt. 2. The level of Mercury remains same while ice melts. This means that temperature is constant. 3. This constant temperature at which ice melts is called melting point of ice and mark it 0 °C. 4. Take some water in a beaker. Immerse the thermometer in it and start heating the water. It will start boiling while getting converted into steam. 5. Mercury level starts rising and reaches a point beyond which it doesn’t rise. Mark the level of mercury at this point. 6. Observe the constant level at which Mercury stays while water is boiling, this constant temperature is called boiling point of water. We mark the level of mercury at this point as 100 °C. 7. Thus temperature at which ice melts or water boils is constant. These values are fixed as 0 °C and 100 °C respectively. Like water, all substances in pure form melt and boil at certain fixed temperatures. 8. To create a scale, we need two fixed points. Let us choose the melting point (0 °C) and boiling point (100 °C) as two fixed points for the scale of thermometer. Now divide the distance between these two points on the thermometer into 100 equal parts. 9. Each of the 100 equal parts represents 1 °C. We further divide 1 °C into 10 small divisions. It can be read as 1/10 = 0.1 °C.
