A pressure of 1 atmosphere is equal to how many Pascals?

The dimensional formula for pressure is:

If the equation $P = \frac{F}{A}$ is dimensionally homogeneous, where $P$ is pressure, $F$ is force, and $A$ is area, what are the dimensions of pressure?

The pressure of a gas is 760 mmHg. What is this pressure in Pascals? (Given 1 atm = 760 mmHg = $1.013 imes 10^5$ Pa)

Which of the following has the dimensions of $ML^{-1}T^{-2}$?

According to the kinetic theory of gases, the pressure exerted by a gas is due to:

If the temperature of a gas is doubled while the volume is kept constant, the pressure will:

A container of fixed volume holds an ideal gas at a pressure $P$ and temperature $T$. If the root mean square speed of the gas molecules is doubled while maintaining the same number density, what is the new pressure?

Two identical containers hold equal moles of two different ideal gases, A and B, at the same temperature. The molar mass of gas A is four times that of gas B. If the average force exerted by the molecules of gas A on the container walls per unit area is $F_A$, and that of gas B is $F_B$, what is the ratio $F_A/F_B$?

A gas undergoes a process where its pressure increases linearly with volume, $P = aV + b$, where $a$ and $b$ are positive constants. If the initial volume is $V_0$ and the final volume is $2V_0$, what is the work done by the gas during this process?
