How does ambient temperature affect gas pressure?

Higher temperatures can increase gas pressure due to the principles established by the ideal gas law, which states that for a given amount of gas in a sealed container, if the volume is kept constant, an increase in temperature will result in an increase in pressure. This occurs because the molecules within the gas move more vigorously at higher temperatures, leading to more frequent and forceful collisions against the walls of the container, thereby increasing the pressure exerted by the gas.

In practical applications, such as in fuel gas systems, higher ambient temperatures can significantly influence the behavior of the gas, leading to higher pressures that may need to be accounted for in system design and operation to ensure safety and efficiency.
