A solution of water is at 0.006atm and 0.01 degrees Celsius. What phase(s) are present in the sample?
Solid, liquid, and gas
Solid and liquid
Liquid and gas
Solid and gas
Liquid only
Explanation
The point detailed in the question is the triple point of water on the phase diagram. At the triple point all three phases of a chemical coexist; as such the correct answer is solid, liquid, and gas.
What is the definition of the triple point?
The state where solid, liquid, and gas coexist in equilibrium
The state where liquid and gas cannot be differentiated
The condensation line of the phase diagram
The point in which temperature change has no effect on the substance
None of these
Explanation
Definition of triple point: where solid, liquid, and gas exist in equilibrium
What is represented by point D
Critical point
Triple point
liquid phase
evaporation
condensation
Explanation
the critical point is where the solid and gas cannot be distinguished
