At a temperature of 500 kelvins, 6 liters of an ideal gas had a pressure of 300 newtons per square meter. if the temperature was reduced to 250 kelvins, and the volume raised to 9 liters, what was the resulting pressure ? (a) 100 newtons/m^2 (b) 150 newtons/m^2 (c) 450 newtons/m^2 (d) 900 newtons/m^2 (e) none of these

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)

Question 3 if the volume of a container is increased, the pressure of the gas in the container also increases (when the amount of gas and temperature are held constant). true false 2 points save answer question 4 to keep the pressure and temperature of a gas constant, the volume of the gas canister must remain constant as additional moles of gas are added. true false 2 points save answer question 5 if the moles and temperature of a gas are held constant, changes in the pressure and volume of the gas will be inversely proportional. true false 2 points save answer question 6 if the moles and temperature of a gas are held constant, the pressure of a gas doubles when: volume is halved volume is quadrupled volume is doubled volume is also held constant 3 points save answer question 7 a bike tire contains a fixed amount of gas at a constant pressure. initially, the tire contains 4.00 iters of air at 26 degrees celsius. when the temperature drops to 22 degrees celsius, the volume of the bike tire will decrease to 3.95 liters. true false 2 points save answer question 8 when using the ideal gas constant value, r = 0.0821, in an ideal gas law calculation, the units of temperature may be expressed as degrees celsius or kelvin. true false 2 points save answer question 9 one mole of a gas has an initial pressure of 2.5 atmospheres, an initial volume of 12.0 liters, and an initial temperature of 150 kelvin. what is the final temperature of a gas if the volume and the pressure are doubled? 75 k 300 k 600 k 1200 k 3 points save answer question 10 initially, a 4.0-liter compressible container of gas exerts a pressure of 2.08 atmospheres at a temperature of 275 kelvin. what is the pressure when the container is compressed to 2.5 liters and has a temperature of 323 kelvin? 1.5 atm 50 atm 3.9 atm 2.8 atm
