Which of the following property is different between water and cooking oil?

Both Option 2 and Option 3 are correct

The correct answer is option 4. Both Option 2 and Option 3 are correct.

Let us break down the differences between water and cooking oil in terms of odor and inflammability:

1. Odor:

Water:  Water is typically odorless. Pure water, in its natural state, doesn't have a distinct smell.

Cooking Oil:  Cooking oils, especially certain types, may have a noticeable odor. Different oils can have different smells, contributing to the overall aroma of the food being cooked.

2. Inflammability:

Water:  Water is not flammable. In fact, it is often used as a fire suppressant because it can extinguish many types of fires by cooling and smothering the flames.

Cooking Oil:  Cooking oils, being hydrocarbons, can be flammable. If the oil reaches its flashpoint and comes into contact with an open flame or heat source, it can catch fire. This is why caution is advised when using cooking oils in the kitchen.

So, both the odor and inflammability properties are different between water and cooking oil. Water is generally odorless and not flammable while cooking oil may have a distinct odor and can be flammable under certain conditions.
