Answer 1

Answer:

A 1. Expansion in solids 2. Volume of water 3. Expansion in gases 4. Evaporation 5. Boiling Column B (a) Highest thermal expansion (b) Surface phenomenon (c) Linear, superficial and cubical expansion (d) Bulk phenomenon (e) 4% increase on heating​

Explanation:

Answer 2

Answer:

This type of boiling occurs in steam tube boilers involving natural convection and in flooded type evaporators of the refrigeration systems. (b) Forced convection boiling: In this case, the fluid motion is induced by external means that is, pump, etc. as well as by free convection and bubble induced mixing.
