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.
40%.
it doesnt have anything to do with that
The volume either increases or decreases
the is more volume in the cone
The volume is changed.
The mass isn't changed. Since the volume is decreased, the quantity (mass/volume) is increased, meaning that the density is increased.
evaporation
by how hard you hit it
the volume of them all stay the same
The volume increases.
No, what you drink goes to the baby too.
You have changed the object's density by increasing its mass without changing its volume. Density is calculated by dividing mass by volume, so as mass increases while volume remains constant, the density of the object will also increase.
