- On a winter day, the air temperature is −5°C, and the humidity is 0.001 kg/m3. (a) What is the relative humidity (in percent)? (b) When this air is brought inside a building, it is heated to 35°C. If the humidity isn't changed, what is the relative humidity (in percent) inside the building?The absolute humidity at atmospheric pressure at 25 ° C is 0.017 kg water / kg dry air. Specify: a. Partial pressure of water vapor. = kPa b. Relative humidity = % c. Dew point temperature. = (°C)Determine at what altitude in meters the air pressure is twice less than on the sea level using the barometic equation that is pressure as a function of height. Given that the temperature is 288.15 K. P=P0e -Mgh/RT, where Po is the pressure at sea level, M is the molar mass of air (in kg/mol), T is standard temperature, R is universal gas constant (8.314 N.m/mol K).

You are going to use a balloon and rise in the corresponding altitudes. If the balloon weighs 1000kg (all included, weight of yourself, equipment, inflated part etc) calculate the volume of inflated part of the balloon, so that the initial acceleration is 15m/s?. Assume that the balloon is a sphere and neglect the deflated part of the balloon as far as volume is concerned. Can you verify all measurements with this volume of the balloon? What kind of adjustments do you need to make in order to complete your mission?

What is the temperature in this region, in degrees Celsius? T =Question 26 Suppose the sun was twice its current temperature. Recall, the sun is 7 x 105 km in radius, with a surface temperature of 5800 K., and our distance from the sun is D = 150 million km. Using the equation to model the temperature of the earth, (sun)1/4 Tsun and remembering you have to work in the absolute temperature 4D² scale (OK = -273°C), what would happen to the temperature of the earth (in Kelvin scale)? It would be a quarter times as hot. It would twice as hot. It would be four times as hot. It would be half as hot.
