Final answer:
The correct answer is B. Liquid level increases, the float rises. A float-type gauge is commonly used in tanks to measure the liquid level.
Step-by-step explanation:
The correct answer is B. Liquid level increases, the float rises.
A float-type gauge is commonly used in tanks to measure the liquid level. It consists of a float that is located inside the tank and connected to an indicator. As the liquid level increases, the float also rises, indicating a higher level of liquid in the tank. Similarly, as the liquid level decreases, the float sinks, indicating a lower level of liquid in the tank.
This type of gauge is considered the safest because no gas is allowed to escape during the process of determining the liquid level. The float simply responds to the change in liquid level, allowing for accurate measurements without any gas leakage.
