Two liquids A and B are mixed and the resulting solution is found to be cooler. What do you conclude about the deviation from ideal behaviour?

Why do real gases deviate from ideal behaviour?

What are the reasons for deviations from ideal gas behaviour ?

If liquids A and B from an ideal solution,

For what reasons does a real gas deviate from ideal behaviour?

If liquids A and B from an ideal solution

10 cm^3 of a liquid A was mixed with 10 cm^3 of liquid B. The volume of the resulting solution was found to be 19.9 cm^3 . What do you conclude?

Which solution shows +ve(positive) deviation from the ideal behaviour ?
