Question

The volumes of gases A, B, C, and D are in the ratio of $1:2:2:4$ under the same conditions of temperature and pressure.

(ii) If the temperature and pressure of gas A are kept constant, then what will happen to the volume of A when the number of molecules is doubled ?

Answer 1

• According to Avogadro's law, under same condition of temperature and pressure equal volume of gases contain equal number of molecules.
• Therefore, at constant temperature and pressure of gas A ,if the number of molecules get doubled then, the volume of the gas will also get doubled.
• Standard Temperature Pressure (S.T.P.):- Standard temperature and pressure, abbreviated STP, refers to nominal situations within the ecosystem at sea level. Standard Temperature and Pressure (STP) is described as zero stages Celsius and 1 ecosystem of pressure.
