Question

an object is kept at surface of water and temperature is increased then fraction of its part outside liquid will increase or decrease​

Answer 1

Answer:

decrease

Explanation:

water density decrease as we increase the temperature so a part of the object will submerged under the water

Answer 2

The fraction of its part outside liquid will decrease.

By increasing temperature, the density of the liquid decreases, so the volume of the body inside the liquid increases to keep the buoyancy force constant for equal to gravitational force.

• The warmer the water, the more space it takes up, and the lower its density.
• When comparing two samples of water with the same salinity, or mass, the water sample with the higher temperature will have a greater volume, and will therefore be less dense.
• When more temperature increases, density reduces. When the temperature decrease, density increases.
• Water has a maximum volume of 4 degrees Celsius and a maximum density of 4 degrees Celsius. But when water is cooled down further its volume starts increasing and hence, the density of water decreases when cooled further below than 4-degree celsius.
• A decrease in temperature caused the water molecules to lose energy and slow down, which results in water molecules that are closer together and a decrease in water volume. When water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense.
