What is evaporation? |
|
Answer» Evaporation happens when a liquid TURNS into a GAS. When liquid water reaches a low enough temperature, it freezes and becomes a solid—ice. When solid water is exposed to enough heat, it will melt and return to a liquid. As that liquid water is further heated, it EVAPORATES and becomes a gas—water vapor.FOLLOW ME & HAVE A NICE DAY |

The displacement of a moving object in a given interval of time is zero. Would the distance travelled by the object also be zero? Justify you answer |
| Answer» E distance travelled by the object also be zero.Explanation :Because displacement IMPLIES that an object has MOVED from one PLACE to another or has been displaced. So , if a object haven't even moved from its initial place it would not have covered any distance EITHER. So, the distance travelled by the object also would be zero. | |
