why doesn’t the water at the bottom of a geyser boil when it is at 100 c?
At the bottom of a geyser, water can reach temperatures well above 100 degrees Celsius without boiling. This is because the pressure inside the geyser is much higher than the pressure at sea level. The higher pressure prevents the water from boiling, even at high temperatures. The relationship between pressure and boiling point is known as the phase diagram of water. The phase diagram shows that the boiling point of water increases as the pressure increases. This means that water can exist in a liquid state at temperatures above 100 degrees Celsius, as long as the pressure is high enough.
In a geyser, the pressure is high because of the weight of the water above it. The deeper down you go in the geyser, the greater the pressure. This means that the water at the bottom of the geyser is under much more pressure than the water at the top. As a result, the water at the bottom of the geyser can reach much higher temperatures without boiling.
When the pressure is released, the water in the geyser boils and erupts. This is because the boiling point of water decreases as the pressure decreases. When the pressure is released, the water at the bottom of the geyser is no longer under as much pressure, so it boils and turns into steam. The steam then rises up through the geyser and erupts out of the top.
what happens when you heat water at 0 c?
Ice, at 0 degrees Celsius, is a solid state of water characterized by rigid molecular bonds, making it hard and brittle. As heat is applied, the molecules gain energy, causing them to vibrate more intensely, breaking the rigid bonds and transforming the ice into liquid water. This phase transition is known as melting.
During melting, the temperature of the water remains at 0 degrees Celsius until all the ice has melted. The heat energy supplied is used to overcome the intermolecular attractive forces, allowing the molecules to move more freely. Once all the ice has melted, the temperature will start to rise again, and the liquid water will eventually boil at 100 degrees Celsius under normal atmospheric pressure.
why should we prefer pressure cooker for cooking?
Pressure cookers are a great choice for cooking because they allow you to cook food quickly and easily. The pressure inside the cooker helps to break down tough fibers, making meat and vegetables tender and juicy. Pressure cookers also help to retain nutrients, so your food is more nutritious than it would be if you cooked it in a regular pot or pan. Additionally, pressure cookers are very energy-efficient, so you can save money on your electric bill. Overall, pressure cookers are a great option for busy people who want to cook healthy, delicious meals quickly and easily.
why cooking is easier in pressure cooker but difficult on hills?
Cooking in a pressure cooker is simpler compared to cooking on hills. Pressure cookers operate by creating a high-pressure environment inside the pot, which expedites the cooking process. This method is particularly useful for foods that typically require longer cooking times, such as beans or tough cuts of meat. Additionally, pressure cookers effectively retain flavors and nutrients within the food, resulting in more flavorful and nutritious dishes. On the other hand, cooking on hills presents several challenges. The primary factor is the reduced atmospheric pressure at higher altitudes. This reduction in pressure affects the boiling point of water, causing it to boil at a lower temperature. Consequently, cooking times are longer at higher altitudes. Furthermore, the reduced atmospheric pressure also impacts the effectiveness of baking, as baked goods may rise differently due to the lower pressure.
why is food cooked quickly in a pressure cooker class 9?
Cooking food in a pressure cooker is a time-saving technique that relies on the principle of increased pressure to elevate the boiling point of water. This enables food to cook more rapidly compared to traditional methods.

This elevated temperature promotes faster cooking times, reducing the amount of time required to tenderize meats, soften vegetables, and prepare various dishes. Additionally, the pressure cooker’s sealed environment helps to retain moisture and nutrients, resulting in flavorful and succulent results.
how long do you pressure cook dry beans?
Dry beans are a versatile and budget-friendly ingredient that can be used in a variety of dishes. Pressure cooking is a quick and easy way to cook dry beans, and it helps to retain their nutrients. When pressure cooking dry beans, it is important to use the correct amount of water. Too much water can make the beans mushy, while too little water can prevent them from cooking evenly. The general rule of thumb is to use twice as much water as beans. If you are using a 6-quart pressure cooker, you will need to use 3 cups of dry beans and 6 cups of water. Once you have added the beans and water to the pressure cooker, close the lid and lock it in place. Set the pressure cooker to high pressure and cook for the recommended amount of time. The cooking time will vary depending on the type of beans you are using. For example, black beans typically take 20 minutes to cook, while pinto beans take 25 minutes. Once the cooking time is complete, let the pressure cooker cool down naturally for 10 minutes. After 10 minutes, carefully release the remaining pressure by turning the pressure release valve to the vent position. Once the pressure has been released, open the lid of the pressure cooker and check the beans. They should be tender and fully cooked. If they are not, you can cook them for a few more minutes. Pressure-cooked dry beans can be used in a variety of dishes, such as soups, stews, and salads. They can also be mashed and used as a spread or dip.
