Answer:
Step-by-step explanation:
An object will float in another if it's density is lower than that of the fluid it is in.
Ice floats in water because ice has a density less than that of water
Wood floats in water because wood has a density less than that of water
Stone sinks in water because it has a density more than that of water
For example, density of water = 1 g/cm³ while the density of ice = 0.9 g/cm³ which is less than 1
