For one mole of an ideal gas,increasing the temperature from $10^{\circ} C$ to $20^{\circ} C$:

When equal volumes of helium and neon at same temperature and pressure are mixed,the ratio $C_p: C_V$ of the mixture equals

The variation of pressure with volume of a gas at different temperatures can be graphically represented as shown in the figure. On the basis of this graph,answer the following questions:
$(i)$ How will the volume of a gas change if its pressure is increased at constant temperature?
$(ii)$ At a constant pressure,how will the volume of a gas change if the temperature is increased from $200 \ K$ to $400 \ K$?

Two thin circular discs $A$ and $B$ of radii $2 \ cm$ and $4 \ cm$ are in a liquid at the same depth. $T_A$ is the thrust on $A$ and $T_B$ is the thrust on $B$. Then $T_A : T_B =$

When $48 \, L$ of dry $N_2$ gas at $27 \, ^oC$ is passed through $36 \, g$ of water,the weight of water decreases by $1.20 \, g$. What is the vapor pressure of water in $atm$?

Assertion : Ice melts faster at high altitude.
Reason : At high altitude,atmospheric pressure is high.
