How many moles of gaseous boron trifluoride, BF_{step three}, are contained in a cuatro.3410-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 leading altitude balloon is stuffed with step one.41 10 4 L off hydrogen during the a fever away from 21 °C and a force of 745 torr. What is the volume of the new balloon on a level away from 20 kilometer, where in actuality the climate is –۴۸ °C as well as the pressure is actually 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 giant diving container ((Figure)) which have an amount of 18 L is actually rated having a force away from 220 bar. The fresh new container try filled on 20 °C and has sufficient air to supply 1860 L out of sky to a diver from the a pressure from dos.37 automatic teller machine (a depth from forty-five base). Is actually this new container filled so you can capability 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 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 babel 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:

Because the step one grams of your own radioactive ability radium decays more than step one seasons, it provides 1.16 10 18 leader dirt (helium nuclei). For every single alpha particle will get a keen atom of helium fuel. What is the pressure inside pascal of your helium energy brought if this uses up a level of 125 mL in the a temperature of twenty-five °C?

An excellent balloon with a volume of L during the 21 °C and you can 0.981 automatic teller machine arrives and just hardly clears the top Mount Crumpet into the United kingdom Columbia. In the event the finally number of this new balloon was L at the an effective temperature of 5.24 °C, what’s the stress knowledgeable from the balloon as it clears Mount Crumpet?

In case your heat out-of a fixed amount of a gasoline was twofold within ongoing frequency, what happens into tension?

If your quantity of a predetermined amount of a gasoline are tripled on lingering temperatures, what takes place toward pressure?

Permit

Solution (a) New normally include some isobutane gas from the a constant volume, so if the temperature try improved by the temperatures, the stress will increase proportionately. High temperature may lead to ruthless, evoking the can be to burst. (Along with, isobutane is actually combustible, therefore incineration can cause the brand new can also be so you can explode.)
