A cubic vessel (with face horizontal + vertical) contains an ideal gas at NTP. The vessel is being carried by a rocket which is moving at a speed of in vertical direction. The pressure of the gas inside the vessel as observed by us on the ground
remains the same because is very much smaller than of the gas
remains the same because motion of the vessel as a whole does not affect the relative motion of the gas molecules and the walls
will increase by a factor equal to where was the original mean square velocity of the gas
will be different on the top wall and bottom wall of the vessel
Get Answer
As the relative velocity of molecule with respect to the walls of container does not change in rocket, due to the mass of a molecule is negligible with respect to the mass of whole system and system of gas moves as a whole and on molecule energy where.
Hence pressure of the gas inside the vessel, as observed by us, on the ground remain the same.
1 mole of an ideal gas is contained in a cubical volume at (figure). One face of
the cube is made up of a material which totally absorbs any gas molecule incident on it.
At any given time,
the pressure on would be zero
the pressure on all the faces will the equal
the pressure of would be double the pressure on
the pressure on would be half that on
Pressure on the wall due to force exerted by molecule on walls due to its rate of transfer of momentum to wall. In an ideal gas, when a molecule collides elastically with a wall, the momentum transferred to each molecule will be twice the magnitude of its normal momentum is . For the wall , absorbs those molecules.
Which strike to it so rate of change in momentum to it become only so the pressure of would half of .
Boyle's law is applicable for an
adiabatic process
isobaric process
isothermal process
isochoric process
Boyle's law is applicable at constant temperature and temperature remains constant in isothermal process. For ideal gas, constant
So, constant (at constant temperature)
So, this process can be called as isothermal process.
A cylinder containing an ideal gas is in vertical position and has a piston of mass that is able to move up or down without friction (figure). If the temperature is increased
both and of the gas will change
only will increase according to Charles' law
will change but not
Volume versus temperature graphs for a given mass of an ideal gas are shown in figure. At two different values of constant pressure. What can be inferred about relation between and ?
Data is insufficient
1 mole of gas is contained in a box of volume at . The gas is heated to a temperature of and the gas gets converted to a gas of hydrogen atoms. The final pressure would be (considering all gases to be ideal)
same as the pressure initially
2 times the pressure initially
10 times the pressure initially
20 times the pressure initially
An inflated rubber balloon contains one mole of an ideal gas, has a pressure , volume and temperature . If the temperature rises to , and the volume is increased to , the final pressure will be
less than
