PHYSICS QUESTION??can u answer it.,class 10th's..................?

Question

choose the correct alternative-
Q-An ice piece floats on pure water in a container fileed upto its rim.On melting of ice piece:-
1-the extra water will flow out of the container
2-the level of the water in th container will fall.
3-neither water will flow out nor the level of the water in the container will fall.
4-the water will flow out of the container as well as the level of the water in the container will fall.
please,answer the question if u really know it,just make ur answer sure and don't guess.Do not create a confusion.

Answer 1

3-neither water will flow out nor the level of the water in the container will fall.
Assuming the ice is pure water the water it displaces will exactly equal the mass of the ice. When it melts it will have lost volume but not matter. After it melts It will then be water exactly equal to the water that it displaced as ice.
Steve (answerer 10) has a good point. The water level will fall as the temperature goes from zero to four degrees. But I think he has overlooked the ice that is above the surface of the water.

Answer 2

3

Answer 3

3

Answer 4

I know you're leaning toward # 3 because of all the support it has garnered here, but it is wrong.
Ice has a density of .917 at 0°C compared with the density of water at the same temp being .9998.
Clearly, when the ice melts it's density will increase and the water level will fall. In fact, it will continue to fall until the temperature of the entire body of water reaches ~4°C, the point of maximum density for water.
#2

Upon reviewing this ?, I decided I made a conceptual mistake in my analysis. #3 is the correct answer, but the volume will decrease from 0° to + 4°C

Answer 5

My answer is option 3 i.e neither water will flow out nor the level of the water in the cotainer will fall because the ice cube is already there in the container and the mass of ice before and after are equal.

Answer 6

Number 3.

Answer 7

ur ans is 3rd option.coz the containar is filled with water so the level of water is up to its rim including with floating ice so when ice melt that water replace the solid ice sono change.

Answer 8

The level of the water in the container will fall.
Water in a solid state is more dense that in a liquid state.

Answer 9

Accelerating is the value at which the value of an merchandise transformations. whilst a ball is tossed into the air gravity on the instant starts off to act on the ball with the intention to strengthen up it. on the grounds that gravity purely acts in the downward direction, gravity can purely generate a metamorphosis in the value of a freefalling merchandise in the downward direction! It would not quite matter huge sort if the ball is shifting upward, downward or is at relax. despite the ball is doing at t=0 seconds, one 2d later the value of the ball would be 9.8m/s greater downward than it replaced into on the initiating. as an occasion, if a ball is shifting upward at 50 meters according to 2d whilst it quite is launched, after a million 2d the value of the ball gets replaced via 9.8 m/s. Vf = 50-9.8 = 40.2 m/sec. So after the a million 2d the ball's upward velocity gets replaced in teh downward direction via 9.8m/s. If the ball is launched from relax, after a million 2d the gravitational rigidity would have lower back replaced its velocity downward via 9.8m/s. Vf = 0-9.8 -9.8 m/s! If the ball is movinf downward at -40 m/s on the 2d it quite is launched, after a million 2d that velocity gets replaced downward via 9.8m/s. Vf = -40-9.9=-40 9.8 m/s. In all 3 circumstances the exchange in the value of the article replaced into in the downward direction! evaluate what might happen if this replaced into no longer real! assume for a 2d that the gravitational acceleration replaced right into a superb 9.8m/s^2! in case you launched a ball below those situations its velocity might exchange in the upward direction! launch a ball drom relax and after a million 2d the ball might then be shifting UPWARD at 9.8 m/s! i'm going to wager which you may locate that to be extremely strange.

Answer 10

2 - The level will fall.
