A sample of methane (CH4) has a volume of 26 mL at a pressure of0.85 atm . What is the volume, in milliliters, of the gas at eachof the following pressures if there is no change in temperature andamount of gas? 1. 0.35 atm 2. 2.30 atm 3. 3100 mmHg The volume ofair in a person's lungs is 626 mL at a pressure of 761 mmHg .Inhalation occurs as the pressure in the lungs drops to 731 mmHgwith no change in temperature and amount of gas. 1. To what volume,in milliliters, did the lungs expand? А sample of neon initiallyhas a volume of 3.00 L at 16 ∘C . 1. What is the new temperature,in degrees Celsius, when the volume of the sample is changed atconstant pressure and amount of gas to 5.50 L ? 2. What is the newtemperature, in degrees Celsius, when the volume of the sample ischanged at constant pressure and amount of gas to 1500 mL ? 3. Whatis the new temperature, in degrees Celsius, when the volume of thesample is changed at constant pressure and amount of gas to 8.50 L? 4. What is the new temperature, in degrees Celsius, when thevolume of the sample is changed at constant pressure and amount ofgas to 3700 mL ? A balloon contains 2500 mL of helium gas at 85 ∘C.What is the new volume of the gas when the temperature changes tothe following, if n (the amount of gas) and P are not changed? 1.40 ∘C 2. 660 K 3. -15 ∘C 4. 235 K
