A kettle of water is heated on a stove. What will happen to the molecules of the water in the kettle as the kettle continues to be heated by the flame?

The molecules will take the heat energy and convert it to mechanical energy and they get "excited" and eventually their bonds will break and they will turn into water vapor.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
