A closed compartment containing gas is moving with some acceleration in horizontal direction. Neglect effect of gravity. Then the pressure in the compartment is
A
Same everywhere

B
Lower in the front side
b The pressure in the front part of the closed compartment will be less because in the accelerated frame the pseudo force will act on the molecules backwards and the density of the gas will be more backwards

A cylinder of fixed capacity $44.8$ litre. contains a monatomic gas at standard temperature and pressure. The amount of heat required to cylinder by $10^o C$ will be. ($R=$ universal gas constant)
Figure shows two flasks connected to each other. The volume of the flask $1$ is twice that of flask $2.$ The system is filled with an ideal gas at temperature $100\, K$ and $200 \,K $ respectively. If the mass of the gas in $1$ be $m$ then what is the mass of the gas in flask $2$
If $10^{22}$gas molecules each of mass $10^{-26}\, kg$ collide with a surface (perpendicular to it)elastically per second over an area $1\, m^2$with a speed $10^4\,m/s$, the pressure exerted by the gas molecules will be of the order of
The air density at Mount Everest is less than that at the sea level. It is found by mountaineers that for one trip lasting a few hours, the extra oxygen needed by them corresponds to $30,000\, cc$ at sea level (pressure $1$ atmosphere, temperature $27°C$). Assuming that the temperature around Mount Everest is $-73°C$ and that the oxygen cylinder has capacity of $5.2 \,litre,$ the pressure at which ${O_2}$ be filled (at site) in cylinder is .... $atm$
An $HCl$ molecule has rotational, translational and vibrational motions. If the $rms$ velocity of $HCl$ molecules in its gaseous phase is $\bar v ,\,m$ is its mass and $k_B$ is Boltzmann constant, then its temperature will be
The temperature of $5$ moles of a gas which was held at constant volume was changed from ${100^o}C$ to ${120^o}C$. The change in internal energy was found to be $80$ Joules. The total heat capacity of the gas at constant volume will be equal to ...... $J/K$
