Sure, here's the step by step explanation:

1. At higher altitudes, the atmospheric pressure is lower than at sea level. This is because the atmosphere is less dense the higher you go above sea level.

2. The boiling point of water decreases as the atmospheric pressure decreases. So, at high altitudes, water boils at a temperature lower than 100 degrees Celsius (the boiling point at sea level). This means that boiling water is not as hot as it is at sea level.

3. Because the boiling water is not as hot, it takes longer to cook food by boiling at high altitudes. This can be inconvenient and also use more fuel.

4. A pressure cooker solves this problem. It is a sealed pot with a valve that controls the steam pressure inside. As the pot heats up, the steam pressure increases, which increases the boiling point of the water inside the pot.

5. This means that the water in a pressure cooker can get hotter than 100 degrees Celsius before it starts to boil. So, food cooks faster in a pressure cooker, even at high altitudes.

6. Therefore, pressure cookers are used for cooking food on hills and other high-altitude locations.
