Question

If you know the mass and volume of an object how can you predict weather it will float or sink in water

Answer 1

IF YOU KNOW MASS AND VOLUME OF A SUBSTANCE THEN CALCULATE THE DENSITY BY APPLYING FORMULA $DENSITY=MASS/VOLUME\frac{x}{y} \frac{x}{y}$

THEN COMPARE IF THE DENSITY OF THAT SUBSTANCE WITH DENSITY OF WATER 1g/cm³

IF LESS THEN IT WILL FLOAT IN WATER

IF MORE THAN THAT THEN IT WILL SINK IN WATER.
