How many moles of gaseous boron trifluoride, BF3, 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 premier altitude balloon is filled with 1.41 ten cuatro L out-of hydrogen from the a temperature from 21 °C and you may a pressure out of 745 torr. What is the quantity of the balloon within a level regarding 20 kilometres, where the weather is –48 °C therefore the tension was 63.step one 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 huge scuba container ((Figure)) having a level of 18 L was rated to own a force away from 220 club. This new container try filled within 20 °C possesses sufficient air to supply 1860 L out-of air in order to a diver from the a pressure off 2.37 automatic teller machine (a degree away from forty-five base). Are new tank filled to strength in 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 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 https://datingranking.net/cs/asiame-recenze/ the volume occupied by 10.0 g of each of these compounds at STP:
As step one g of the radioactive feature radium decays more than 1 year, it provides step 1.sixteen ten 18 alpha dirt (helium nuclei). For every leader particle becomes an enthusiastic atom off helium fuel. What is the pressure inside pascal of helium fuel brought whether it uses up a number of 125 mL within a fever regarding twenty-five °C?
A beneficial balloon which have an amount of L in the 21 °C and you can 0.981 automatic teller machine arrives and just scarcely clears the top of Mount Crumpet during the Uk Columbia. If the last amount of the fresh new balloon try L within an excellent temperature of five.twenty-four °C, what is the stress knowledgeable by the balloon since it clears Mount Crumpet?
Should your temperatures out of a predetermined number of a gasoline is doubled from the ongoing regularity, what goes on with the stress?
When your volume of a predetermined amount of a gas was tripled from the ongoing temperature, what are the results into the stress?

Provider (a) The fresh new can be include some isobutane gasoline from the a stable volume, therefore if heat try enhanced by the temperatures, the pressure will increase proportionately. High heat could lead to ruthless, inducing the is to-burst. (And, isobutane was combustible, very incineration trigger the new is in order to burst.)
Look at the Training What’s the volume of an example of ethane within 467 K and you will step 1.step 1 automatic teller machine whether it takes up 405 mL during the 298 K and you will 1.step one atm?
Check your Studying Estimate the pressure when you look at the bar off 2520 moles of hydrogen fuel stored in the twenty seven °C from the 180-L storage tank of a modern hydrogen-driven vehicle.
Simple Requirements off Temperatures and you may Tension
The amount regarding an auto air bag was 66.8 L whenever excessive within twenty-five °C which have 77.8 g regarding nitrogen energy. That which was the stress from the bag within the kPa?
