Cooking in a pressure cooker cuts your cooking time down to about a third. In other words, if you would normally cook a roast for 3 hours it's only going to take 1 but keep in mind that were talking really high temperatures here. The pressure at which you cook the meat at will also cause the time to vary, as will as the fact that top round roasts have very little fat content, quite the opposite of a chuck roast. I usually cook a 3 lb top round roast for about an hour. The process is basically the same as what you would normally cook a top round roast at except for a few added steps. Heat up your pressure cooker and add about 2 to 3 tablespoons oil. Cut your roast into four equal parts, salt and pepper each piece and then brown on all sides. Remove meat from cooker and add about 1 cup beef broth along with 3/4 cup Italian salad dressing. If your presser cooker has a lift pan to keep the meat off of the bottom of the pan while cooking, insert it at this time and cover. Cook for about 1 hour. If you would like to include potatoes and carrots with this meal, have your potatoes and carrots cut, seasoned and ready to go once the roast is done cooking. When the roast is done cooking, take the entire cooker (lid still on!) over to the sink and run cold water over it. This will very quickly bring the internal pressure down to normal allowing you to open the cooker and add your vegetables (unless your roast is completely falling apart, leave the roast in the cooker and add vegetables on top, other wise remove the meat and keep covered and warm). Return cooker to the stove top, replace lid and bring the pressure back up. Once the pressure is where you want it cook for an additional 20 minutes.
why do we use pressure cooker at hill stations for cooking food
If the cooker was not off for longer than four hours yes.
A pressure cooker minimizes the escape of fluids or air. The build-up of air and fluid increases the pressure inside the cooker, which also increases the boiling point. An open kettle allows the fluid and air to escape, heat is lost thus cooking time is longer.
The greater the pressure the water is under the greater the heat required to bring it to boiling point.
Yes, but it might not be as tender as cooking it on low for a longer period of time. Just be sure to keep enough water/broth in the slow cooker to make sure your roast doesn't dry out too much.
pressure cookers cook faster. Instead of cooking something for 3-4 hours you can cut that down to maybe 1 hour. It tenderizes meat by forcing the steam into the food and breaking up some of the molecules

If you are referring to cooking with a pressure cooker, the higher pressure attained in this type of cooker allows the water to reach a higher temperature before boiling. This will cook food more quickly due to the higher temperature, which in turn is due to the higher pressure. Keep in mind that once water reaches the boiling point, the temperature remains constant; the only way to attain a higher temperature, then, is to increase the pressure.
Boiling point = temperature where the vapour pressure is equal to the pressure of the atmosphere above the liquid. When you have a pressure cooker, the pressure above the water is higher than atmospheric pressure, therefore the boiling point of water is elevated to above the boiling point in an open pot. The water temperature exceeds 100 degrees Celsius, and thus the cooking process is accelerated.
The answer would depend on the pressure attained by the cooker.
