Which gas law states that for a fixed volume, increasing temperature increases pressure?

Explanation:
When you keep the volume fixed and raise the temperature, the gas molecules move faster and collide with the container walls more vigorously and more often. Those more forceful collisions push the pressure higher. This direct, proportional relationship between pressure and temperature at constant volume is Gay-Lussac's Law. Remember to use absolute temperature (Kelvin) in the proportionality, often written as P1/T1 = P2/T2. This is different from Charles' Law (volume changes with temperature at constant pressure), Boyle's Law (pressure changes with volume at constant temperature), and Avogadro's Law (volume changes with amount of gas at constant T and P).
