Rajah 3 menunjukkan sebiji buah anggur di dalam bikar X dan bikar Y. Mengapakah buah anggur itu timbul di dalam bikar Y?Diagram 3 shows a grape in beaker X and in beaker Y. Why does the grape float in beaker Y?
Beaker X: the grape is at the bottom. Beaker Y: the grape floats at the top of the water.
