It indicates that the temperature does not change during the phase change from liquid to gas until the change is complete. During the phase change, the heat energy added to the water goes into breaking hydrogen bonds between water molecules, so it does not cause an increase in temperature during that time.
The plateau indicates that during the transition from liquid to gas, the temperature stays the same.
This indicates that that the water is changing form from a liquid to a gas.
In a closed system the entropy is constant.
To remove the water of hydration. the loss of weight will be the weight of water present in the original salts.
So that the temperature of the liquid is at a constant measurement
Because the color spectra of stars indicate which elements are present.
The boiling point.
This indicates that that the water is changing form from a liquid to a gas.
Any gas will expand when heated, assuming you keep pressure constant.
it will boil once it reaches 100 degrees Celsius
because of its high elevation.
yes
Mass
The pressure is higher.
In a closed system the entropy is constant.
Heated liquid rises because it reaches the boiling point.
One is for constant pressure, the other is for constant volume. These are not the same; for example, if the pressure is maintained constant, and the gas is heated, the volume changes.
Generally, if air is heated, its temperature will increase. And if the pressure remains constant, its density will decrease.
