Stoichiometry The crystallisation of a solute from a solution may be done by All of these Change of temperature thereby causing supersaturation Changing the nature of the system by the addition of a more soluble material Removal of pure solvent by evaporation All of these Change of temperature thereby causing supersaturation Changing the nature of the system by the addition of a more soluble material Removal of pure solvent by evaporation ANSWER DOWNLOAD EXAMIANS APP
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 work equal to loss in kinetic energy Do not lose energy on collision Do not exert attractive force on each other Are above the inversion temperature Do work equal to loss in kinetic energy Do not lose energy on collision Do not exert attractive force on each other ANSWER DOWNLOAD EXAMIANS APP
