Is the relationship between the amount of gas and pressure direct or indirect? Explain your answer

guajiro [1.7K]

Answer:

INDIRECT!

see below

Step-by-step explanation:

A law that says that if the temperature is constant then the volume of a fixed amount of a gas is <u>inversely proportional</u> to its pressure.If the pressure on a gas increases, the volume of the gas decreases because the gas particles are getting closer together.
