Mixture of ice and water is form a

1. Closed System
2. Open System
3. Isolated System
4. Heterogeneous System

Answer 1

In chemistry a mixture is a material which is made up of two or more different substances which are physically combined. The identities of both the substances which are together remains intact.

Complete step by step Solution:
Closed System: A closed system is physical in nature and does not allow the transfer of matter inside or outside of a defined system. In terms of physics a closed system does not allow transfer of energy inside or outside the defined system. In the situation given in the question there is no such defined condition, so the mixture of ice and water is not a form of closed system.
Open System: Unlike the closed system in which there is no transfer of energy or transfer of matter occurring inside or outside the system, in the open system there is a transfer of energy happening inside and outside of the system. Since, there is no such defined system given in the question therefore the mixture of ice and water is not a form of open system.
Isolated System: An isolated system like a closed system in which no energy or heat transfer can occur. Isolated system means that it is very far away from any other systems so that it is impossible to interact. Since, in the given question there is no such mention therefore the mixture of ice and water is not an isolated system.
Heterogeneous System: A heterogeneous system is a system in which two or more homogenous bodies are merged or available. Two bodies are said to be homogenous if their material and chemical properties are the same. The homogenous bodies which are present inside a heterogeneous system are called phases. Each of one homogenous body is separated from another homogenous body by interfaces, boundary, physical property, etc. Here, ice and water have the same material and chemical properties but their physical properties are different. Water is in liquid form and ice is in solid form. Therefore, the mixture of ice and water is in the form of a heterogenous mixture.

Final Answer: Option “4” is correct. Therefore, the mixture of ice and water is forming a heterogenous mixture.

Note: Here, define each system given in the question and provide a proper explanation as to why the given option is not the correct option. Then explain the reason for the mixture of ice and water being a heterogenous mixture.
