During heating the pressure increase in the pressure cooker; as a consequence the temperature increase, the cooking is faster, part of energy saved, etc.
When the dry ice is placed on the cooker it will explode, unless the temperature of the cooker is at a low degree.
Do you mean how can you boil at different temperatures? You can add lots of salt to the boiling water to raise the temperature. This isn't very effective. The best method is to pressurize the pot (pressure cooker) this will raise the temperature quite a bit, up to 250 degrees at the highest pressure allowed by a pressure cooker. Do you mean what are the different temperature scales and boiling points? water boils at 212 degrees F or 100 degrees C
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.
You can know when you have reached the right cooker pressure by checking the temperature gauge. The right temperature would also depend on what you are cooking.
An increase in pressure allows an increase in the boiling temperature of the liquid in the cooker. At 15 psi (the highest rated home kitchen pressure cooker) the boiling temperature of water is 250 degrees F.

Yes it does.
At higher pressures, water boils at a higher temperature. A pressure cooker lets you cook at a higher pressure than regular saucepans so you can have a higher boiling temperature
yes pressure cooker is an example for both charles' law and boyle's. under constant volume temperature is directly proportional to pressure, where the pressure is directly proportional to temperature. so when the stove heats the cooker it increase the in the pressure which in turn increase the internal temprature and cooks the food faster....
By heating the pressure increase and again the temperature increase.

The universal gas law states that (pressure * volume/temperature) of a gas is a constant. Hence, if the volume stays the same (as in a pressure cooker), the air in the cooker can increase in temperature beyond the boiling point of water as pressure builds up over the normal atmospheric pressure. A higher temperature means faster cooking. The above is a very simplistic view of the physics involved.
