Question

In an open system, which of the following takes place ?
a. The boundaries prevent the flow of matter into or out of it.
. The boundaries prevent the flow of energy into it.
c. The boundaries prevent the flow of matter but not of energy.
d. The boundaries permit the flow of matter into or out of it.​

Answer 1

Answer:

Open System is any thermodynamic system which allows exchange of matter and energy in between the interior of the system and the surroundings.

So the boundaries actually permit the flow of both mass and energy in and out of the system.

Examples of Open System :

A classic example is the Human Body which actually transmits both mass and energy in and out of the system.

Another example is heating soup in Saucepan. So both heat and mass is transferred to the surroundings in the form of water vapour.

This transmission results in changes in both the system and the surroundings.

So the closest option is :

$\boxed{\red{option \: D}}$

AnsWer:-

In an open system, which of the following takes place ?

a. The boundaries prevent the flow of matter into or out of it.

. The boundaries prevent the flow of energy into it.

c. The boundaries prevent the flow of matter but not of energy.

d. The boundaries permit the flow of matter into or out of it.

ExplainaTion:-

★Open system is that system which allows exchange of both matter and energy from surrounding to system or system to surrounding.

Hence, the boundaries of open system permit the flow of matter into or out of it.

Related Terms:-

★ Isolated system:- which does not allow exchange of both matter and energy between system and surrounding.

★ Closed system:- Which allows only exchange of energy but not matter between system and surrounding.
