A soft keyboard (sometimes called an onscreen keyboard or software keyboard) is a system that replaces the hardware keyboard on a computing device with an on-screen image map.
The ideal gas law can be viewed as arising from the kinetic pressure of gas molecules colliding with the walls of a container in accordance with Newton's laws. But there is also a statistical element in the determination of the average kinetic energy of those molecules. The temperature is taken to be proportional to this average kinetic energy; this invokes the idea of kinetic temperature. One mole of an ideal gas at STP occupies 22.4 liters.
The Universal Gas Constant-Ru-appears in the ideal gas law and can be expressed as the product between the Individual Gas Constant-R - for the particular gas-and the Molecular Weight-Mgas-for the gas, and is the same for all ideal or perfect gases : Ru = Mgas R (1). where. Ru = universal gas constant.
