Final answer:
The variable representing the pressure exerted by the gas is C) Pressure. Pressure is the force per unit area caused by gas molecules colliding with the container walls and can be influenced by volume, temperature, and the amount of gas present.
Step-by-step explanation:
The variable that represents the pressure exerted by the gas is C) Pressure. Pressure is defined as the average force per unit area exerted by the gas molecules when they collide with the walls of their container. The pressure (P) of a gas can be influenced by the volume (V) it occupies, the temperature (T) it is subjected to, and the quantity of gas present, often measured in moles (n).
In the scenario given, the gas occupies a volume of 0.5 m3 and exerts a force of 2,400 N on the walls of the container. To find the pressure exerted by the gas, we would divide the force by the area over which it is applied, in accordance with the formula P = Force / Area. Thus, the correct answer is C) Pressure.
Boyle's Law further illustrates the relationship between pressure and volume, describing how they are inversely proportional to each other at a constant temperature. If the volume of a container decreases, the pressure of the gas increases, and vice versa. This relationship is described by the formula P = k/V, where k is a constant.
