Question
Boiling of the liquid is due to __________
- Force
- Friction
- Heat
- Grease
Hint:
Heat transfer results in the boiling of water.
The correct answer is: Heat
- Convection is the process of heat transfer in fluids.
- When the water is heated in a pan , the molecules of water that are at bottom takes up the heat and rises up.
- The colder and heavy molecules comes at the bottom .
- This generates the circulating current in the water that heats up the whole water.
- Hence boiling of water occurs due to heat .
