The complete statement will be "Support gases system are subject to the same hazards as, present in any piped medical gas system with the additional hazard of higher pressure"
<h3>What are gas systems?</h3>
Generally, A gas system is simply defined as an assemblage of tubes, used for gas reticulation and circulation.
In conclusion, a higher pressure will be experienced as an additional hazard to the medical gas system.

It is important to compare the positive and negative test results with those of known compounds as positive results indicate the presence of that known compound and negative results indicate the absence of that compound which is used for reference.
<h3>What is qualitative analysis?</h3>
Qualitative chemical analysis is a method to determine the chemical composition of a sample.
There are two types of qualitative analysis:
- Organic Qualitative analysis: It helps in determining the chemical bonds and functional groups in a sample
- Inorganic qualitative analysis: It helps in determining the ions in the given sample
There are seven ways to analyze a sample qualitatively, which are
A reference compound is always used to which results are compared.
A Positive result indicates that the reference compound is present in the sample whereas a negative result indicates that the reference compound is absent in the given sample.

The distance between molecules INCREASES when the substance vaporizes
Explanation:
The distance between the molecules increase due to the fact that as you put more energy into the substance the kinetic energy of the molecules increases. This means they are vibrating more vigorously and the collision between the molecules are becoming more energetic. This means the collisions fling the molecules far away from each other (due to their increased momentum) hence the increased average distance between molecules.

Answer:
True
Explanation:
GIBBS FREE ENERGY (G) Gibbs free energy is a thermodynamic function It is a state function. G = H - TS At constant temperature At constant pressure and temperature An increase in S corresponds to a decrease in free energy
Constant free energy (G) P, T The important thing about free energy is that whenever the pressure and temperature are constant, we can determine the spontaneity of a process only in terms of the thermodynamic properties of the system G = H - TS The Free energy change is a measure of the change in the total entropy of a system and its environment at constant temperature and pressure. <u>Spontaneous processes at constant temperature and pressure are accompanied by a decrease in free energy</u>.
At constant temperature and pressure, the direction of spontaneous change is towards the lowest free energy. <u>The equilibrium state of a system corresponds to the lowest point of the free energy curve
</u>.
