What is the still water level?

The still water level is the highest level that water reaches after a flood event. It represents the maximum height to which water has risen and remained static before receding. It is a key indicator of the extent of flooding in a particular area.


How do the mass and height of an object affect the gravitational potential energy?

The gravitational potential energy of an object is directly proportional to both its mass and height above the reference point. As the mass of the object increases, so does its gravitational potential energy. Similarly, as the height of the object increases, its gravitational potential energy also increases.


Is height extensive or intensive?

Height is an intensive property because it does not depend on the amount of the substance present. It remains the same regardless of the quantity.


What is the HETP in continuous distillation?

It is height equivalent to a theoretical plate(hetp).HETP is related to the height of packed columns provided to separate a mixture of volatile substances. in distillation the number of trays required for efficient separation is obtained by knowing the height of the packed column when it is done in packed bed reactors.. so HETP=height of the column/number of trays.


How can you make the height of the flame smaller on a Bunsen burner?

To make the height of the flame smaller on a Bunsen burner, you can adjust the air hole at the base of the burner. By opening the air hole slightly, less oxygen will reach the flame, leading to a smaller and more controlled flame height.
