The temperature of the sun, if pressure is $$1.4 \times 10^9$$ atm, density is $$1.4 gcm^{-3}$$ and average molecular weight is 2, will be
$$[Given\  R = 8.4  J  mol^{-1} K^{-1}]$$

What is new gauge pressure?

A barometer tube 90 cm long contains some air above mercury. The reading is 74.8 cm when true atmospheric pressure is 76 cm and temperature is 30$$^o$$ C. If the reading is observed to be 75.4 cm on a day when temperature is 10$$^o$$C, then find the true pressure.

Two containers of equal volume contain the same gas at pressures $$P_1$$ and $$P_2$$ and absolute temperatures $$T_1$$ and $$T_2$$, respectively. On joining the vessels, the gas reaches a common pressure $$P$$ and common temperature $$T$$. The ratio $$\displaystyle\frac{P}{T}$$ is equal to

One mole of an ideal gas undergoes a process $$P = \displaystyle \frac{P_o}{1 + \left ( \displaystyle\frac{V}{V_o} \right )^2}$$, where $$P_o$$ and $$V_o$$ are constants. Find the temperature of the gas when $$V = V_o$$.

The African bombardier beetle stenaptinus insignis can emit a jet of defensive spray from the movable tip of its abdomen. The beetle's body has reservoirs of two different chemicals. When the beetle is disturbed, these chemicals are combined in a reaction chamber producing a compounds that is warmed from $$20^o$$C to $$100^o$$C by the heat of reaction. The high pressure produced allows the compound to the sprayed out at speeds 19 ms$$^{-1}$$ scaring away predators of all kinds. Assume specific heat of two chemicals and the spray to be same as that of water $$[4.19 \times 10^3 J (kgK)^{-1}]$$ and initial temperature of chemicals to be $$20^o$$C. How many times does the pressure increase?

The correct graph between PV and P of one mol of gas at constant temperature will be

A gas is filled in a container at any temperature and at pressure 76 cm of Hg. If at the same temperature the mass of gas is increased by 50% then the resultant pressure will be

In the gas equation $$PV= RT$$, V is the volume of

An enclosure of volume 3 litre contains 16g of oxygen, 7g of nitrogen and 11g of carbondioxide at 27$$^o$$C. The pressure exerted by the mixture is approximately
