Stoichiometry Unrestrained expansion of an ideal gas does not result in its cooling due to the reason that the gas molecules Are above the inversion temperature Do not exert attractive force on each other Do not lose energy on collision Do work equal to loss in kinetic energy Are above the inversion temperature Do not exert attractive force on each other Do not lose energy on collision Do work equal to loss in kinetic energy ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry If the absolute temperature of an ideal gas is tripled and simultaneously the pressure is reduced to one third; then the volume of gas will Remain unaltered Decrease three fold Increase nine fold Increase three fold Remain unaltered Decrease three fold Increase nine fold Increase three fold ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry One mole of methane undergoes complete combustion in a stoichiometric amount of air. The reaction proceeds as CH₄ + 2O₂ → CO₂ + 2H₂O. Both the reactants and products are in gas phase. ΔH°298 = - 730 kJ/mole of methane. If the average specific heat of all the gases/vapour is 40 J/mole.K, the maximum temperature rise of the exhaust gases in °C would be approximately equal to 1525 1335 1735 1225 1525 1335 1735 1225 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Specific gravity on API scale is given by the relation(where, G = specific gravity at 15.5°C). °API = (141.5/G) - 131.5 °API = 200(G - 1) °API = 145 - (145/G) °API = (140/G) - 130 °API = (141.5/G) - 131.5 °API = 200(G - 1) °API = 145 - (145/G) °API = (140/G) - 130 ANSWER DOWNLOAD EXAMIANS APP
