Identify the type of system if boiling water is kept in a half filled closed vessel.
Homogeneous closed system
Heterogeneous closed system
Homogeneous isolated system
Heterogeneous isolated system
Solution
In order to determine the type of system when boiling water is kept in a half-filled closed vessel, let's analyze the key characteristics of the system.
A system can be one of the following types based on its interaction with its surroundings:
Homogeneous System: A system that has a uniform composition and properties throughout its volume. For example, a solution of salt in water.
Heterogeneous System: A system that consists of two or more phases with different compositions and properties. For example, water and oil mixture.
Closed System: A system that exchanges energy (heat and work) but not matter with its surroundings. A sealed container is an example of a closed system.
Isolated System: A system that does not exchange energy or matter with its surroundings. A perfectly insulated and sealed container can be considered an isolated system.
Now, let's apply this information to the given scenario:
When boiling water is kept in a half-filled closed vessel:
Since the vessel is closed, it does not exchange matter with its surroundings, but it can exchange energy in the form of heat. Inside the vessel, there are two distinct phases present: liquid water and water vapor (steam), which makes it a heterogeneous system.
So, combining these characteristics, the system is a:
Heterogeneous closed system.
Thus, the correct option is:
Option B: Heterogeneous closed system
