Topic: Practice exercise on gas laws. You must write the equation you are using to solve the exercise. 1. A sample of Argon gas occupies an initial volume of 5.40 L when its pressure is 6.52 atm. What will be the final pressure of the gas if its volume increases to 9.73 L? 2. An unknown gas occupies an initial volume of 0.256 L when its temperature equals 121ºC. What will be the final volume if the temperature drops to...
Question 5 What effect would a decrease in temperature have on pressure, assuming that volume (T) and moles of gas (n) are kept constant? Group of answer choices Pressure would decrease. Pressure would stay the same regardless of a change in temperature. Pressure would increase Question 6 Which temperature scale has NO negative values? Group of answer choices Farenheit Digital Kelvin Celcius Question 7 Calculate the number of moles of gas with a volume of 35.0 L at a temperature...
