Neon is a gas at room temperature.
In order for molecules in a solid state to change to a liquid state, the substance needs to be heated. An increase in temperature causes more molecular movement (this leaves more space between each molecule) which results in what we see as the physical change from solid to liquid and then eventually liquid to gas.
The difference in the physical states of butter and mustard oil at room temperature is due to their different compositions of fats and oils. Butter contains a higher proportion of saturated fats which are solid at room temperature, while mustard oil is mainly composed of unsaturated fats which are liquid at room temperature. The structure and arrangement of the fat molecules in each substance determine their physical state.
oil molecules get tighten each other.
Solidification of water depends on both temperature and pressure. Experimental phase diagrams are available in any text book on the subject. For a given pressure (in most circumstances) once the temperature is below the solidification point, reducing the temperature generally will not change its state.
It is a chemical change because the sodium(Na) is a liquid that forms with a yellow gas, chlorine(Cl), which changes the physical state to a dickmuncher solid, but ultimately they reacted with each other chemically to form salt (NaCl). It does change the physical state, but it is more of a chemical reaction.
A substance can take on three physical states: Solid, liquid, or gas. The main physical changes from a thermodynamic standpoint are the amount of entropy(disorder) of the molecules of the substance. Density, temperature, volume are also characteristically different at each physical state and can be used to manipulate compounds between the three.
The transformation of a physical state of a substance into a different physical state is called a phase change. An example of this is water changing from solid (ice), to a liquid (water), to a gas (steam).
It all depends on the individual State requirements. Each State in the US regulates physical therapists, and depending on which State you are working in, you will have the designation of PT or MD physical therapist.Check with your local State board as to which one they regulate.

Licensure is done by each state so you need to check your state for their qualifications. The American Board of Physical Therapists is the governing board.

Other substances with molecules of a similar state are indeed in a gaseous state, at room temperature. It seems that water is liquid, at room temperature, because of its large electric dipole, which causes molecules to attract each other more than is usual for molecules of that size.Other substances with molecules of a similar state are indeed in a gaseous state, at room temperature.

Yes, the chemical properties of water will stay the same even when the physical properties are being changed (phase change).
