<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:
kinetic energy
Explanation:
Thermal Energy, Temperature, and Heat. Thermal energy is kinetic energy associated with the random motion of atoms and molecules.
A physical change is when something don't permanently change
Answer:
3H2SO4 + 2B(OH)3 -> B2(SO4)3 + 6H2O
Explanation:
Answer:
The four stages of technological design include identifying a need, designing and implementing a solution, and evaluating the solution.
I don't know what the options are, cause you didn't show them but, hope this helped.
