Atmospheric Sciences 101 Name_________________Autumn.2006 Student #______________Section________________Homework #1Due: Thursday, October 5, 2006 at the beginning of classPlease show your work.1. Fill in the blanks:98.6°F= ________ °C = ________°K25°C= _______ °F = ________°K190°K= ________ °C = _______°F14.7 lb/in2= _______inches of Hg = ______mb10 knots= ________ mph = ______m/s25 cm= ________ inches70 feet= ________m25 miles= ________km2. A particular field of snow is heavily crusted over. This crust can support apressure of 1 lb. per square inch before it collapses. A 240-lb. man with two skis 3inches wide and 60 inches long tries to ski over the snow. What is the pressure(lbs. per square inch) on the snow due to skis? Will the skier collapse the snowcrust?3. On a clear night the temperature at a surface station fell from 25°C to 15°C. Fogbegan to form when the temperature reached 17°C. What is the dewpointtemperature?4. If we used a liquid twice as dense as mercury in a barometer, approximately howhigh would the column of that liquid be under normal sea level conditions?5. How much does the kinetic energy of the wind change as wind speed increases by50%? Since the wind's kinetic energy is a measure of its destructive power, whatdoes that imply regarding damage? 6. In class we talked about the Torricelli barometer, in which a long testtube full of mercury was inverted into a dish of mercury (see figurebelow). Assuming that the atmospheric pressure is P, answer thefollowing:a. At point A in the test tube, located at the height of the top of themercury in the dish, what is the downward pressure forced by themercury column?ABb. At point B at the top of the mercury column, what is the pressure?c. If the atmospheric pressure increases, what will happen to theheight of the mercury
