Yes, it is true.
Pressure Cookers raise the boiling point of water. As pressure increases on a liquid, so does the boiling point. This is due to the fact that a liquid will not boil until the vapor pressure of the liquid is equals the environmental pressure surrounding the liquid. Think of it essentially as the surrounding pressure holds the substance in liquid form until it has enough energy to escape into gas form.
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
Dissolving salt in water increases the boiling point of water. This is because the salt disrupts the hydrogen bonds between water molecules, making it more difficult for them to escape as vapor. As a result, more heat is needed to raise the temperature of the solution to its boiling point.
Increasing pressure on the surface of water raises the boiling point of water. This is because higher pressure traps more heat energy in the liquid, thus requiring a higher temperature to overcome the increased pressure and boil.
No, pure ammonia will not always boil at the same temperature due to variations in pressure. The boiling point of ammonia is approximately -33.34 °C at standard atmospheric pressure. However, if the pressure changes, the boiling point will also change; higher pressures raise the boiling point, while lower pressures decrease it. Therefore, the boiling temperature of ammonia is dependent on the surrounding pressure conditions.
Increasing the air pressure in the pot will raise the boiling point of water. This is because with increased pressure, water molecules require more energy to overcome the higher pressure and vaporize, leading to a higher boiling point than at normal atmospheric pressure.

By increasing the pressure on the water, you can raise its boiling point above 100°C. This can be achieved in a pressure cooker, where the increased pressure allows the water to reach a higher temperature before boiling.
If you want and if it is possible by an increase of pressure.

the boiling point of the water will raise 3 deg. frht. for every pound of pressure the cap is rated for. a 10lb. cap will raise the boiling temp to 242deg. frht.
Dissolving salt in water increases the boiling point of water. This is because the salt disrupts the hydrogen bonds between water molecules, making it more difficult for them to escape as vapor. As a result, more heat is needed to raise the temperature of the solution to its boiling point.
No, the boiling point of the pure water remain constant at 100 0C, of course at standard pressure.
Increasing pressure on the surface of water raises the boiling point of water. This is because higher pressure traps more heat energy in the liquid, thus requiring a higher temperature to overcome the increased pressure and boil.
Yes, by increasing the pressure you raise the boiling point.
If the lid is tight enough to raise the pressure in the pan (as in a pressure cooker), the boiling temperature will be higher. However, if the lid just sits loosely on top, it will make the water boil sooner because not as much heat is lost and the water heats up faster.
salt or sugar would lower the melting point and raise the boiling point. The salt or sugar would reduce the partial pressure of water in the solution (essentially more competition), effectively raising the boiling point.
