If the container decreases in size, the pressure inside the container will increase. This is because the gas molecules are more confined and collide more frequently with the walls of the container. The amount of gas remains constant, but the pressure changes due to the reduced volume.
According to Gay-Lussac's law, if the temperature of a fixed amount of gas at constant volume decreases, the pressure of the gas must also decrease. This relationship is directly proportional; as temperature drops, the kinetic energy of the gas molecules decreases, resulting in fewer collisions with the walls of the container and thus lower pressure.

Boyle's Law states that at constant temperature, the volume of a gas is inversely proportional to its pressure. This means that as the pressure of a gas increases, its volume decreases, and vice versa.
...pressure decreases.
If the temperature of the gas is lowered, its pressure will decrease as well, assuming the volume remains constant. This is because as the temperature decreases, the average kinetic energy of the gas molecules also decreases, leading to fewer collisions with the container walls per unit of time, resulting in lower pressure.
When the pipe diameter decreases, the gas flow becomes more restricted, causing an increase in pressure. This is known as the Venturi effect, where the fluid velocity increases as it passes through a constricted section, leading to a decrease in pressure.
