A pure gas may be made up of individual atoms (e.g. Greenhouse gas, any gas that has the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the greenhouse effect. Elasticity-Elasticity is the property by virtue of which a body regains its original size and shape after the removal of deforming force is called elasticity and the deformation caused is called elastic deformation.B. 0000001348 00000 n Thefirstsubstancestobeproduced andstudiedinhighpurity weregases. 0000000016 00000 n Gases have played an important part in the development of chemistry. 0000007564 00000 n At high pressures and low temperatures the finite molecular volume and inter-particle interactions can no longer be omitted. 0000012880 00000 n xref 0000000596 00000 n In this experiment you will investigate the properties of sulfur dioxide (SO2) and nitrogen dioxide (NO2), two gases … In the seventeenth and eighteenth centuries, many scientists investigated gas behavior, providing the first mathematical descriptions of the behavior of matter. The gases are made up of a large number of molecules and they are flying in a random direction with a certain speed. If the boiling point of a substance is below 273 K, then the substance to be in gas form at STP. ��#�з��f�0V2K[�5pt�Hf��`��@�� , I��f`�R�i�� Q��D3it ��l�m@M��K> i � ��Z`�x��E�� \��Y�/�;p��j�//�%��!��^�0 �0 ٦� – McGraw-Hill Poling B.E., Prausnits J.M., O’Connell J.P., Language: english. 0000001701 00000 n Molecules are not entities with point masses.
