Set up two containers with me; one will be open and one will be covered. Leave them for several days. What will happen to the water level in each container after several days?
1) The water level in the open container will decrease and the water level in the covered container will remain the same.
2) The water level in the open container will remain the same and the water level in the covered container will decrease.
3) The water level in both containers will decrease.
4) The water level in both containers will remain the same.
