Final answer:
The components of the ideal gas law that pertain to the respirometers with the germinated pea seeds are pressure, volume, temperature, and amount of gas. The water moves down the pipet in the respirometers due to differences in pressure caused by the consumption of oxygen by the germinated pea seeds.
Step-by-step explanation:
The components of the ideal gas law that pertain to the respirometers with the germinated pea seeds are:
Pressure (P): This is the force exerted by the gas on the walls of the respirometer.
Volume (V): This is the space occupied by the gas inside the respirometer.
Temperature (T): This refers to the average kinetic energy of the gas molecules.
Amount of gas (n): The number of gas molecules present in the respirometer.
The water moves down the pipet in the respirometers because of the movement of gases due to differences in pressure. As the germinated pea seeds respire and consume oxygen, the oxygen concentration inside the respirometer decreases. This creates a lower partial pressure of oxygen inside the respirometer compared to the surrounding environment, causing the water in the pipet to be displaced downward.
