Statement I: Cooking time is reduced in a pressure cooker.

Statement II: Boiling point of water inside is elevated.

Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I

The correct answer is option 1. Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I.

Statement I is correct because the boiling point of water inside a pressure cooker is elevated. This is because the pressure inside the pressure cooker is higher than the atmospheric pressure, which means that the water needs to reach a higher temperature in order to boil.

Statement II is also correct because the elevated boiling point of water inside the pressure cooker reduces the cooking time. This is because the food cooks faster at a higher temperature.

Statement II is the correct explanation of Statement I because it explains why the cooking time is reduced in a pressure cooker. The elevated boiling point of water inside the pressure cooker allows the food to cook faster.

Here are some additional explanations:

A pressure cooker is a pot with a lid that locks tightly. The lid has a valve that allows steam to escape from the pot, but it also prevents air from entering the pot. This creates a higher pressure inside the pot than the atmospheric pressure.

The boiling point of water is the temperature at which water changes from a liquid to a gas. The boiling point of water increases with pressure. This means that water will boil at a higher temperature in a pressure cooker than it will in an open pot.

The higher boiling point of water in a pressure cooker allows the food to cook faster. This is because the food cooks faster at a higher temperature.
