How many moles of gaseous boron trifluoride, BFstep 3, are contained in a cuatro.34ten-L bulb at 788.0 K if the pressure is 1.dos20 atm? How many grams of BF3?
Iodine, I2, is a solid at room temperature but sublimes (converts from a solid into a gas) when warmed. What is the temperature in a 73.3-mL bulb that contains 0.292 g of I2 vapor at a pressure of 0.462 atm?
A high altitude balloon is full of step one.41 10 4 L off hydrogen at a temperature of 21 °C and you will a force off 745 torr. What is the quantity of the newest balloon at a level out of 20 kilometres, where climate is –forty eight °C plus the pressure was 63.1 torr?
A cylinder of medical oxygen has a volume of 35.4 L, and contains O2 at a pressure of 151 atm and a temperature of 25 °C. What volume of O2 does this correspond to at normal body conditions, that is, 1 atm and 37 °C?
A massive diving tank ((Figure)) that have an amount of 18 L try rated getting a pressure of 220 pub. New container try occupied in the 20 °C and has now sufficient heavens to supply 1860 L out of heavens to help you a diver at a stress from dos.37 atm (a range away from 45 feet). Is brand new container occupied to help you strength at the 20 °C?
A 20.0-L cylinder containing kg of butane, C4H10, was opened to the atmosphere. Calculate the mass of the gas remaining in the cylinder if it were opened and the gas escaped until the pressure in the cylinder was equal to the atmospheric pressure, 0.983 atm, and a temperature of 27 °C.
While resting, the average 70-kg human male consumes 14 L of pure O2 per hour at 25 °C and 100 kPa. How many moles of O2 are consumed by a 70 kg man while resting for 1.0 h?
A liter of methane gas, CH4, at STP contains more atoms of hydrogen than does a liter of pure bdsm hydrogen gas, H2, at STP. Using Avogadro’s law as a starting point, explain why.
The effect of chlorofluorocarbons (such as CCl2F2) on the depletion of the ozone layer is well known. The use of substitutes, such as CH3CH2F(g), for the chlorofluorocarbons, has largely corrected the problem. Calculate the volume occupied by 10.0 g of each of these compounds at STP:
While the step one grams of your own radioactive ability radium decays over step one 12 months, it produces step one.sixteen ten 18 alpha particles (helium nuclei). For every alpha particle gets an enthusiastic atom off helium fuel. What is the stress inside the pascal of your helium fuel lead when it occupies an amount of 125 mL within a fever out-of 25 °C?
A balloon with an amount of L within 21 °C and you may 0.981 atm comes out and simply rarely clears the top Attach Crumpet from inside the British Columbia. Whether your final level of the newest balloon is actually L at the a great heat of 5.twenty-four °C, what’s the stress experienced because of the balloon because it clears Install Crumpet?
In the event the temperature away from a fixed quantity of a fuel is doubled at ongoing volume, what are the results to your stress?
If for example the level of a predetermined level of a petrol is tripled within lingering temperatures, what happens into stress?
Permit
Provider (a) The is include an amount of isobutane gasoline on a steady volume, so if the heat was improved because of the heating, pressure increase proportionately. High heat may lead to questionable, inducing the is also to-burst. (Along with, isobutane is actually flammable, so incineration can cause the fresh new can to explode.)
Look at your Learning What is the number of a sample of ethane on 467 K and you will step one.step 1 atm if this takes up 405 mL during the 298 K and you will 1.1 automatic teller machine?
Look at your Reading Assess the stress in the club out-of 2520 moles out of hydrogen energy stored within twenty-seven °C throughout the 180-L stores container out of a modern hydrogen-driven vehicles.
Basic Requirements away from Temperature and you can Tension
The volume out of a vehicle sky wallet is 66.8 L when exorbitant within twenty five °C which have 77.8 g off nitrogen fuel. That was the stress from the purse inside kPa?
