pressure conversion unit

Pressure - There are many situations in which effects of a force are better described in terms of force per unit area i.e. pressure..

Pressure - When a force is applied on a surface in a direction perpendicular to the surface, the force is called thrust. Pressure on a solid surface is the thrust per unit area of the surface. Pressure is a scalar quantity. The SI unit of Press..

Solubility of a gas in a liquid increases with the increase in partial pressure of the gas above the solution. Quantitatively, this is governed by Henrys law, which states that at constant temperature. The mass of a gas dissolved in a given volume of the liquid is directly proportional ..

The maximum height of mercury, which can be supported by the atmospheric pressure provides a measure of that pressure. A standard pressure of one atmosphere (1 atm) is defined as the pressure that will support a column of mercury of 76 cm height at 0C (densi..

Why does a gas exert pressure on the walls of container? Consider only those molecules which are moving horizontally. Each molecule hits the container wall and bounces back with the same speed, because the collision is elastic. The molecule then travels in the opposite direction. During ..

If N is the total number of molecules in the sample, we can write The pressure is force per unit area so that where M is the total mass of the gas taken and r is its density. Also, is the average of the speeds squared. It is written ..

Inter-conversion of the States of Matter - Depending on the conditions of temperature and pressure, matter can exist in any of the three main states i.e., solid, liquid or gas. Matter can be inter-converted from one state to the other by the addition or removal of heat energy. A..

To convert Celsius scale to Kelvin scale, add 273 to the Celsius temperature. 32 o F = 0 + 273 = 273 K 212 o F = 100 + 273 = 373 K -459.4 o F = - 273 + 273 = 0 K To convert Kelvin scale to Celsius scale, subtract 273 from the Kelvin scale. 0 K = 0 - 273 = - 523.4 o F 273 K = 273 - 273 = 32 o..

.e., the volume of the container. The unit of volume: 1 litre = 1 dm 3 = 1000 cm 3 or 1000 ml. Pressure exerted by a gas is the average force exerted due to the bombardment of the particles on the sides of the container per unit area of the container. The unit..

then forces the water to move up inside the straw and into our mouth. In the same way, atmospheric pressure forces a liquid to move into a syringe when its plunger is withdrawn [figure (b) shown above]. Rubber suckers are used for installing hooks in the kitchen and bathroom. The air betw..
