Answer 1

SOLUTION ANSWERY Extensive : extensive propervies are physical properties that deponos or amount of matter. mass, volume, length.... on mass examples intensive :- etc... vintensive propertiesare physical properties that is independent on the mass amount of mat ter. ex (12 density, Boiling, pressure, temperet, surface tension, vi viscosity. etc.., Isothermal process: - in this process temperature remains constant called isothermal process. 1-sobaric process: - in isobaric process pressure remains conseomt is called isobaric process.

Saturated liquid :- is about to vaporize is Saturated ugu'd. A Liquid that called saturated vapour :- about condense A that is vapor vapool. called saturated the Quality x liquid ratio of mass of vapor to telle mess of the mixture. Saturated liquid to set vapor -y1 Psaturated vapor Superhelted Vapor A vapor cis about to condense. vapor not about to condense. * lower enthalpies * Higher entheepy valle, + lower vinternal Higher internal energy. energy.
