• The principle used in the pressure cooker is that the boiling point of water increases with an increase in pressure. Hence option (a) is the correct answer.
• Pressure cooker has a confined space sealed from all side (except valve which is used to release excess pressure). When heat is supplied to the cooker it first increases the temperature of the water. When the temperature of the water reaches 100 degrees Celsius (water's boiling point at atmospheric pressure) some of it starts converting to steam and starts filing the confined pressure cooker space.
• Since steam is gaseous, it takes more space than water and covers all the vacant space insider cooker. With further heating, it reaches a point where there is no more space for the gaseous steam in the cooker and due to confined volume/space in the cooker, it gets compressed.
• This compression increases the pressure inside the cooker to more than atmospheric pressure which in turn increases the boiling point of the remaining water (as the boiling point of water increases with increasing pressure).
• Now the water which could go only up to 100 degrees Celsius under atmospheric pressure, goes beyond100 degrees Celsius.
• Higher temperature of water means higher transfer of heat to food kept in it and hence the faster cooking.

Explanation:
Pressure cookers work by increasing the pressure inside the cooking vessel, which in turn raises the boiling point of water. This increase in pressure allows the food to cook faster than it would in a regular pot or pan. Here's a detailed explanation of why food cooks faster in a pressure cooker:
Increased Pressure:
- When the pressure inside a pressure cooker is increased, it also increases the boiling point of water.
- In a regular pot, water boils at 100 degrees Celsius (212 degrees Fahrenheit) at sea level.
- However, in a pressure cooker, the boiling point of water can increase to around 120-130 degrees Celsius (248-266 degrees Fahrenheit) due to the increased pressure inside the cooker.
Faster Cooking Time:
- Because the boiling point of water is higher in a pressure cooker, food cooks faster as it is exposed to higher temperatures.
- This higher temperature leads to quicker cooking times, which is why pressure cookers are often used to cook foods that typically take longer to cook, such as tough cuts of meat or dried beans.
Efficient Cooking:
- By cooking food faster, pressure cookers also help to save energy and reduce cooking time.
- This makes pressure cookers an efficient and convenient cooking tool for busy individuals or those looking to save time in the kitchen.
In conclusion, food cooks faster in a pressure cooker because it increases the boiling point of water by increasing the pressure inside the cooking vessel.
