A cork is floating in salty water. As more salt is added to the water to increase its density, the cork will
2 answers:
Answer:
Float more above the water level
Explanation:
As we know that during flotation of the force balance equation is given as
weight of the cork is balanced by the buoyancy force due to liquid
so here we can say
V = volume of submerged part of the cork
now we have
now as we add more salt in the water then the density of water will increase due to which the submerged part of the volume will decrease as we know that it is inversely depends on density of the water
so here submerged volume will decrease so cork will float more part above the liquid level

To solve the problem, we can use Charle's law, which states that for an ideal gas at constant pressure the ratio between absolute temperature T and volume V remains constant:
For a gas transformation, this law can be rewritten as
(1)
where 1 and 2 label the initial and final conditions of the gas.
Before applying the law, we must convert the temperatures in Kelvin:
The initial volume of the gas is
, so if we re-arrange (1) we find the new volume of the gas:

Answer:
Explanation:
Here by energy equivalence we can say that energy given by the metal piece is same as the energy absorbed by the water
so here we have
here we know that
