प्रश्न
Why is the floating ice less submerged in brine than in water?
उत्तर
Density of brine is more than the density of water. Hence, the upthrust exerted by brine is more than the upthrust exerted by water on ice. Therefore, floating ice is less submerged in brine.

How does an object’s density determine whether the object will sink or float in water?
Assertion: To float, body must displace liquid whose weight is equal to the actual weight.
Reason: The body will experience no net downward force in that case.
