-Pwrite-ups are far apart-Move freely-Fill the easily accessible space-Gases have actually relatively low densities.-Gases create a solution in any kind of proportions
-Gases expand also as soon as heated and shrink once cooled. The volume adjust is 50 to 100 times greater for gases than for liquids and also solids.

Force________Area- Atmospheric press arises from the pressure exerted by atmospheric gases on the earth"s surface- Atmospheric press decreases through altitude
= 760 mmHg (millimeters of mercury)= 760 Torr= 101.325 kPa (kilopascal)= 14.7 Psi (pounds per square inch)(lb/in^2 or psi)
A geochemist heats a limestone (CaCO3) sample and also collects the CO2 released in an evacuated flask attached to a closed-end manometer. After the mechanism pertains to room temperature, Δh = 291.4 mm Hg. Calculate the CO2 push in torrs, settings, and also kilopascals.
n and also T are constantPV = (nRT) = constantP goes up as V goes down-At resolved T and n, P decreases as V increasesP rises as V decreases-At constant temperature, the volume occupied by a fixed amount of gas is inversely proportional to the external pressure.-A bicycle pump is a good example of Boyle"s legislation. As the volume of the air trapped in the pump is lessened, its pressure goes up, and air is required right into the tire.
If n and P are continuous, thenV = (nR/P)T = kTV and T are proportional.-V and T Have a direct relationship-At solved P and n, V decreases as T decreasesV rises as T increases-At consistent press, the volume occupied by a solved amount of gas is directly proportional to its absolute (Kelvin) temperature.

"Equal quantities of gases at the same T and P have actually the same variety of molecules."V = (RT/P)×n = k×nV and n are straight proportional.-Twice as many type of molecules provides twice the sizeonce T & P continuous. 8 H2 + 4 O2 --> 8 H2O
(volume of 1 mole of an ideal gas at STP)From P V = n R T1 mol of any gas = 22.4 liters (molar volume) at STP (conventional temperature press R= 0.0821 (latm/mol
k)
STP or traditional temperature and push specifies a press of 1 atm (760 torr) and a temperature of 0°C ( 273.15 K).The conventional molar volume is the volume of 1 mol of a suitable gas at STP.Standard molar volume = 22.4141 L or 22.4 L
