what is the relationship between the volume and pressure of gases at constant temperature?

The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law). Under the same conditions of temperature and pressure, equal volumes of all gases contain the same number of molecules (Avogadro's law).

This empirical relation, formulated by the physicist Robert Boyle in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k, a constant. ...

So, in summary, the Ideal Gas Law states that under the same temperature, pressure and volume all gases contain the same number of molecules (but not the same mass).

1 Answer. The combined gas law relates the variables pressure, temperature, and volume whereas the ideal gas law relates these three including the number of moles.

Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa, when the temperature is held constant.

The pressure and temperature of any gas, including air, are directly proportional, according to Gay-Lussac's law. This gas law shows that, if the mass and volume of any given sample of gas are held constant, as the sample's temperature increases, so too will its pressure, and vice versa.

This relationship between pressure and volume is known as Boyle's lawA law that states that at constant temperature, the volume of a fixed amount of a gas is inversely proportional to its pressure., after its discoverer, and can be stated as follows: At constant temperature, the volume of a fixed amount of a gas is ...

When the volume decreases, the pressure increases. This shows that the pressure of a gas is inversely proportional to its volume. This is shown by the following equation - which is often called Boyle's law.

Measurement of Temperature on the Ideal Gas Scale. ... On this scale temperature has been defined as proportional to the product of PV for a fixed mass of gas. If the volume of the gas is kept constant, then the temperature is proportional to the pressure of the gas.

P = Pressure (atm) V = Volume (L) n = moles R = gas constant = 0.0821 atm•L/mol•K T = Temperature (Kelvin) The correct units are essential. Be sure to convert whatever units you start with into the appropriate units when using the ideal gas law.

Lesson Summary. Particles of a gas are constantly moving and bumping into things. This gives gases pressure. The gas laws describe the relationship among pressure, volume, and temperature of a given amount of gas.

According to your graph, what is the relationship between pressure and volume? Volume (V), is inversely proportional to the pressure (P). When the pressure of gas increases, the volume of gas decreases.

Answers and Replies. What this means is that pressure * volume is proportional to temperature. So if you go from 20->40 C, the pressure * volume increases by (40+273)/(20+273) or about 6%.

vV ^P ^V vP the relationship is inverse. Pressure and temperature will both increase or decrease simultaneously as long as the volume is held constant. Therefore if temperature were to double the pressure would likewise double.

Charles' Law: The Temperature-Volume Law. This law states that the volume of a given amount of gas held at constant pressure is directly proportional to the Kelvin temperature. As the volume goes up, the temperature also goes up, and vice-versa.

Charles's law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale when the pressure is held constant. with k being a proportionality constant that depends on the amount and pressure of the gas.
