Question

question 20
boyles law select is constant
charles law select is constant
volume
temperature
pressure

Explanation:

Step1: Recall Boyle's Law

Boyle's Law states that for a given mass of an ideal gas at constant temperature, the pressure and volume are inversely proportional. So the constant quantity in Boyle's Law is Temperature.

Step2: Recall Charles's Law

Charles's Law states that for a given mass of an ideal gas at constant pressure, the volume is directly proportional to the absolute temperature. So the constant quantity in Charles's Law is Pressure.

Answer:

For Boyle's law: Temperature is constant.
For Charles's law: Pressure is constant.
