Constant pressure refers to a condition where the pressure remains unchanged during a process or reaction. It allows for the measurement of other variables, such as volume and temperature, without pressure affecting their values.
A gas law that states that at constant temperature, the volume of a fixed amount of gas is inversely proportional to its pressure.
Charles's Law: A gas law that states that at constant pressure, the volume of a fixed amount of gas is directly proportional to its temperature.
A gas law that states that at constant volume, the pressure of a fixed amount of gas is directly proportional to its temperature.
