Say we start with a solid. The molecules vibrate around fixed points, little movement. When temperature rises, these molecules gain kinetic energy and spread out to form a liquid. The molecules are moving faster, colliding into each other every so often. Temperature rises again and the molecules reach the gas phase.
The same when temperature decreases but just the opposite.
What else can I help you with?
What causes substances to change phases?
The pressure and temperature mostly the temperature.
What is the solvus temperature?
The solvus temperature is the temperature at which a solid solution phase transitions into a two-phase region with separate phases. Above the solvus temperature, the solid solution will start to decompose into distinct phases.
What are the various phases of an instruction cycle Give the micro operation of fetch and decode phases?
there are 4 phases in instruction cyclefetchdecodeexecutestore
How are the conditions pressure and temperature at which two phases coexist in equilibrium shown on a phase diagram?
By a line separating the phases
What is a phase diagram?
a diagram showing the effects of temperature and pressure on phase
What is the temperature at which vapor pressures of solid and liquid phases are the same?
The temperature at which the vapor pressures of the solid and liquid phases are equal is called the triple point. At the triple point, all three phases (solid, liquid, and gas) can coexist in thermal equilibrium.
What happens as the moon revolves around the earth?
we get different phases of the moon
Why does the temperature remain constant when it boils?
A substance has different phases, but it only boils at a certain temperature. If it is over that temperature it will evaporate or if it is under that temperature it won't boil.
What is the temperature at which a substance may exist in all three phases?
The temperature at which a substance may exist in all three phases (solid, liquid, and gas) simultaneously is known as the triple point. At the triple point, the substance's vapor pressure, temperature, and phase equilibrium are all in balance, allowing for coexistence of all phases.
What do the lines on a phase diagram represent?
The lines on a phase diagram represent the boundaries between the different phases of a substance (such as solid, liquid, and gas). These lines show the conditions of temperature and pressure at which two phases can exist in equilibrium with each other.
How are the conditions of pressure and temperature at which two phases coexist in equilibrium shown on a phase diagram?
By a line separating the phases
What is the term for the temperature at which a substance changes phases from a solid into a liquid?
Melting point
