List of top Physics Questions on Pressure

The pressure exerted by $5$ moles of a real gas in one litre vessel at $47^??$ is $(a = 3.592 \,atm\, L^2\, mol^{-2}$, $b = 0.0427\, L\, mol^{-1})$
Two soap bubbles have radii in the ratio of 2:1. What is the ratio of excess pressures inside them?
Two capillaries of same length and radii in the ratio $1 : 2$ are connected in series. A liquid flows through them in streamlined condition. If the pressure across the two extreme ends of the combination is $1 \,m$ of water, the pressure difference across first capillary is
The volume of an air bubble increases by x% as it rises from the bottom of a lake to its surface. If the height of the water barometer is H, the depth of the lake is
The two femurs each of cross-sectional area $10 \,cm^{2}$ support the upper part of a human body of mass $40\, kg$. The average pressure sustained by the femurs is $(Take\, g = 10\, m\, s^{-2})$
The $SI$ unit of pressure gradient is
The pressure and density of a diatomic gas $\left(\gamma=\frac{7}{5}\right)$ change adiabatically from $\left(P, ?\right)$ to $\left(P? If $\frac{\rho'}{\rho}=32$, then $\frac{P '}{P}$ is
The level of water in a tank is 5m high. A hole of area $1\,cm^2$ is made at the bottom of the tank. The rate of leakage of water from the hole in $m^3/s$ is $(g=10\,ms^{-2})$
The density of water at the surface of the ocean is $\rho$ and atmospheric pressure is $p _{0}$. If the bulk modulus of water is $K$, what is the density of ocean water at a depth where the pressure is $n p_{0}$ ?
The density of air at N.T.P. is 1.293 gm/lit. If the pressure is tripled keeping its temperature constant its density becomes
Pressure is a scalar quantity because
Pressure at a point inside a liquid does not depend on
A crowbar of length 120 cm has its fulcrum situated at a distance of 20cm from the load. The mechanical advantage of the crow bar is
Mercury boils at $367^{\circ}C$. However, mercury thermometers are made such that they can measure temperature upto $500^{\circ}C$. This is done by
Two spherical soap bubbles of diameters 10 cm and 6 cm are formed, one at each end of a narrow horizontal glass tube. If the surface tension of the soap solution is 0.03 Nm$^{-1}$, then the pressure difference in pascal between the two ends of the tube is
