- If the dew point of air (35°C and 1 atm) is 20 °C, what is the RH under that temperature and pressure (35°C and 1 atm)? What is the volume fraction?The temperature 7 in a metal sphere is inversely proportional to the distance from the center of the sphere where the origin is at (0, 0, 0). The temperature at point (1, 2, 2) is 117°C. (a) Find the rate of change of the temperature at point (1, 2, 2) in the direction toward point (2, 1, 3). - 13 √3 (b) Determine the direction of greatest increase in temperature. XTwo containers of equal volume each hold samples of the same ideal gas. Container A has 2 times as many molecules as container B. If the gas pressure is the same in the two containers, find the ratio of the the absolute temperatures TA and TB ( i.e TA / TB ) . Calculate to 2 decimals.
- Liquid nitrogen has a boiling point of−190.52◦C at atmospheric pressure.Express this temperature in degreesFahrenheit.Answer in units of ◦F Express this temperature in Kelvin.Answer in units of K.In everyday experience, the measures of temperature most often used are Fahrenheit F and Celsius C. Recall that the relationship between them is given by the following formula. F = 1.8C + 32 Physicists and chemists often use the Kelvin temperature scale. You can get kelvins K from degrees Celsius by using the following formula. K = C + 273.15 (a) Calculate that value.K(25) = (b) Find a formula expressing the temperature C in degrees Celsius as a function of the temperature K in kelvins. C = (c) Find a formula expressing the temperature F in degrees Fahrenheit as a function of the temperature K in kelvins. F = (d) What is the temperature in degrees Fahrenheit of an object that is 272 kelvins?The pressure P (in kilopascals), volume V (in liters), and temperature T (in kelvins) of a mole of an ideal gas are related by the equation PV = 8.317.
