Reflection occurs with light waves only, not sound or water waves.

The correct answer is 200°C

Explanation:

Boiling point is defined as the temperature at which liquid state starts to convert into gaseous state. It is an intensive property.

Intensive property is defined as the property which does not depend upon the amount of substance. It remains same.

Extensive property is defined as the property which depends upon the amount of substance. Its value changes as the amount of substance changes.

Boiling point of a substance will not change for given mass of substances.

Boiling point of water = 100°C

Boiling point of soybean oil = 300°C

From the given table:

Value of M = 100°C

Value of N = 300°C

So, the difference in the values of N and M = (300 - 100)°C= 200°C

Hence, the correct answer is 200°C
