Is Alcohol vaporizing physical change or chemical change?
Alcohol vaporizing is a physical change because it does not involve a change in the chemical composition of the alcohol molecules. It is simply a phase change from liquid to gas.
Is boiling alcohol and then considering the vapor a chemical change?
Yes, boiling alcohol and considering the vapor is a physical change as it does not alter the chemical structure of the alcohol molecules. The alcohol vapor can be condensed back into liquid alcohol without undergoing a chemical change.
What is the relationship between polarity and vapor pressure?
They are inversely related. The volatility of a liquid increases with decreasing vapor pressure, as it provides more reversible effect on liquid molecules, so less liquid molecules are able to escape. Conversely, the volatility of liquid increases with decreasing vapor pressure, as it provides less reversible effect on liquid molecules, allowing more to escape.
Does alcohol change into gas?
Yes, alcohol readily changes to a gas (vapour) at room temperature.
During which phase change does the average distance between molecules always increase?
During the phase change from a liquid to a gas, the average distance between molecules always increases.
How does the density of Isopropyl alcohol change with temperature?
As temperature increases, the density of isopropyl alcohol decreases. This is due to the thermal expansion of the liquid, where the molecules move further apart, causing the density to decrease. Conversely, as temperature decreases, the density of isopropyl alcohol increases.

How volume of alchool is changed?
When mpc gel is immersed in various water/alcohol mixtures, a change in the gel volumes will be observed depending on not only the composition of the alcohol in the mixture but also in the chemical structure of the alcohol. In water/monohydric alcohol mixtures, the mpc gel will have an irregular swelling behavior with the change of a composition in the alcohol. Showing the so called reentrant volume phase transition. these volume phase transitions strongly depend on the hydrophobic group, the polarity of the alcohol. On the other hand polyhydric alcohol does not affect the swelling of the mpc even when the composition of the alcohol was changed. This suggest that , water molecules hydrated on the poly chains are with drawn by hydration of the alcohol molecules and the volume of the mpc gel is decreased. Therefore is good agreement to the hydration ability of the alcohol and it's polarity.

How does the speed of molecules change when ice change to water?
Their speed - Kinetic Energy - increases as the solid melts.
What makes an increase temperature change the reaction rate?
It increases the collisions that result in a reaction. or it increases the kinetic energy of the molecules.
What makes in increase in temperature change the reaction rate?
It increases the collisions that result in a reaction. or it increases the kinetic energy of the molecules.
Does mixing borax and polyvinyl alcohol result in a chemical change?
Mixing borax and polyvinyl alcohol does not result in a chemical change. Instead, it forms a physical change known as cross-linking, where the borax molecules create bonds with the polyvinyl alcohol molecules to form a flexible slime-like material.
Does alcohol change into gas?
Yes, alcohol readily changes to a gas (vapour) at room temperature.
During which phase change does the average distance between molecules always increase?
During the phase change from a liquid to a gas, the average distance between molecules always increases.
