Question

2 The number of phases in a mixture of O2. N2 and CO2 gases are... (A)zero (B)one (C)two​

Answer 1

Answer 2

The correct option is B.

• The region of space where the physical properties of materials maintain uniformity is called phase.
• For example, if we add oil to water then two-phase forms between water and oil. From this phase, we can easily distinguish between water and oil separately.
• The mixture of Nitrogen, Oxygen and carbon dioxide is homogeneous. So, only one phase will exist.
