Randomized Variables n = I. 6 moles V= 0.058 m3 :l {g 50% Part (a) The initial pressure of the gas is 1 atm. What is the initial temperature (in K) of the gas? {I} 50% Part (b) The pressure of the gas is increased to 10 atm. Now what is the temperature (in K) of the gas? T=| {9%}! Problem 3: Suffose a 23C car tire contains 3.85 moi of gas in a 3.7.." L volume. A 50% Part (a) What is the gauge pressure, in atmospheres, of the gas in the tire? & 50% Part (D) What will be the gauge pressure, in units of atmosphere, if you add a quantity of gas that had a votume of 2.00 L when it was at atmospheric pressure and the same temperature as the tire? Assume the temperature returns to 23C and the volume remains constant. Pg.2=' (9%) Problem 4: Suppose 1.95 liters of gas at 37.5 .C is under 7.39 x 10 pascals of pressure. How many moles of gas are there in the system? n = mol(9%) Problem 5: 9.5 kg of water (c = 4186 J/(kg.K)) is heated from T1 = 14.50 C to T, = 21.5 C. 4 33% Part (a) Input an expression for O, the heat transferred to the water. A 33% Part (b) Calculate the value of heat, in units of joules, transferred to the water. A 33% Part (c) 0.5 kg of water at T3 = 20 C is added to the heated water. What is the final temperature of the water, in units of kelvin? Tf = K(9%) Problem 6: An electric coffeemaker has a 710-W heating element. The specific heat of water is 4.19 x 103 J/(kg. C). How long, in seconds, does it take the coffeemaker to heat 0. 77 L of water from 18C to 98 C, assuming all the heat produced by the heating element goes into the water? At =
