Answer:
1.)The water in the container number 1 evaporated. Whenever water is heated, the energy from the heat causes the molecules to vibrate rapidly and move away or move apart from each other. When it the water boils and reaches its boiling point, the energy from the heat converts the water into gas or vapor.
2.)2 decreases compared to the water in container No. ... The water in container number 2 evaporates and leaves the container empty since it has no cover. While the water in container No. 1 are trap inside and the cover have some droplets on it.
3.)The water molecules increases its kinetic energy by absorbing heat in the environment making its molecule to spread apart and resembles the particle pattern of gas molecules and will eventually turns into gas.
4.)no, no difference will happen it will evaporate as it uses the temparature of a room.. Container no. 2 is uncovered so the water came out of it..
