Answers
Answer:
fire
doesn't have a shadow cause fire is itself a source of light, so the wall or obstacle you'd be expecting it's shadow to fall on, would instead be covered by the light from the fire. Hence, fire has no shadow
water
When you leave the glass of water uncovered for about 12 hours, carbon dioxide in the air starts to mix with it. This reduces the pH level of the water and gives it an off taste. But even then this water is safe to drink. Moreover, most experts believe that tap water has a shelf life of six months.
Answer:
1] Shadow is formed when an object stops the path of light which causes a dark area behind the object. Fire doesn't have a shadow cause fire is itself a source of light.
2] It happens due to evaporation. For few days, the glass water would evaporate causing the water getting half that.
