Answer:
The given substances are classified based on their solubility in water:
1. Sugar- soluble
2. Mustard seeds- insoluble
3. Drops of coconut oil- insoluble
On pouring the given substances in water and stirring, we observe:
The soluble substances completely mix with water whereas the insoluble ones form a separate layer without mixing.
Sugar gets dissolved in water completely to form a homogenous mixture.
Mustard seeds and coconut oil are immiscible and they form a separate layer- sink or float in water depending on their density ( mustard seeds sink whereas coconut oil floats).
Coconut oil does not mix with water as water is a polar solvent and coconut oil is non-polar in nature.
