2) (a) What is the rms-speed of the Nitrogen molecules at 25 degrees Celsius? = 32g/mol = 28g/mol (b) Calculate the average speed for Nitrogen at 25 degree Celsius. (c) What is the average translational KE of a Nitrogen molecule at 293 K? 3A) One (1) mole of an ideal gas receives an input of 360J of energy in the form of heat. The gas does 325J of work on its surroundings by expanding Pg.2 temperature change . 3B) An ideal gas is undergoing isothermal processes. Constant temperature. adiabatically while doing 1500 J of work on its surroundings. Calculate it temperature change. 4) (a) Calculate the work done by an ideal gas undergoing an isobaric process. The pressure of the gas is 4.8 x 10^5 Pa The initial volume is 4m^3. The final volume is 8m^3. (b)What is the change in internal energy of the gas if 4000 kJ of energy is supplied? 5) An aluminum flagpole is 300 cm high. (a) By how much does its length increase as the temperature increases by 20 degree Celsius? (b) What is the total length of the flagpole? The coefficient of linear expansion for aluminum is = Alpha = 24 x 10^(-6)/degree Celsius. 6) 0.5 kg of hot water at 98.6 degree Celsius is poured into a 0.18 kg glass bowl initially at 25 degrees Celsius. What will be the common final temperature of the water and bowl when equilibrium is reached? Requirements: Show work While diving in Cancun Mexico where the seawater has a density of 1015 kg/m3 Nana observed that her pressure meter device reading was 3.75 atm. The reading at sea level is the standard 1.0 atm. At what depth is she diving when the meter read 3.75atm? Find the change in its internal energy. Using your answer from part a) calculate the What amount of heat Q is added to the gas so that the Gas does 5030 joules of work on the environment. 0.5 moles of an ideal monatomic gas expands
