An ideal gas is defined as one in which all collisions between atoms or molecules are perfectly eleastic and in which there are no intermolecular attractive forces. One can visualize it as a collection of perfectly hard spheres which collide but which otherwise do not interact with each other.
Happy to help
<h2>Hello!</h2>
The correct answer is A: Water molecules evaporate and condense at the same rate.
<h2>Why?</h2>
Evaporation is defined as the physical change from liquid to gas, and Condensation is the physical change from gas to liquid.
At any given temperature, these two processes occur at once, in a dynamic equilibrium.
When the lid is closed, evaporation occurs faster than condensation, and pressure increases. Then, when pressure reaches a critical value, condensation starts to occur faster than evaporation, until an equilibrium is reached, and the pressure of the water molecules in the gas phase is maximum for that temperature. The pressure at that point is called Vapor Pressure.
Have a nice day!
Answer:
Explanation:
The states that all of the particles that make up matter are constantly in motion. As a result, all particles in matter have kinetic energy. The kinetic theory of matter helps explain the different states of matter—solid, liquid, and gas. ... Particles do not always move at the same speed.
