Question

Answer True or False to the following statements.

When two liquids are mixed at constant T and P, the volumes are always additive.

When two liquids are mixed at constant T and P, there is always some heat transfer with the surroundings.

Answer 1

1) When two liquids are mixed at constant T and P, the volumes are always additive.( False )

explanation:

When two liquids are mixed at constant T and P it the resultant solution is idela then the volumes are additive otherwise not addiitive . the resultant solution may be positively diviated or negatively deviated .so this is false

2) When two liquids are mixed at constant T and P, there is always some heat transfer with the surroundings (False)

explanation:

heat transfer depends on flask we have taken . if flask is made up of insulator there is no heat transfer . so we cannot say always heat transfer
