Select the diagram that depicts the change in volume of a gas sample in a container when the pressure and the Kelvin temperature of the system are both tripled.

The following diagrams are at a constant temperature of 40°C. Select the diagram that depicts a gas sample exerting the lowest pressure.

Consider two tanks with identical volumes, and both are at the same temperature. The first tank contains 3.5 g of F₂ gas, while the second tank contains 3.5 g of Cl₂ gas. Determine whether the following statement is true or false. Justify your answer. 

The pressure in the first tank is greater than the pressure in the second tank.

The ideal gas equation is PV = nRT. In the equation, P and V are
