Quick Answer: Why Does Water Rise When You Put Something In It?

What makes water rise?

Because twice as much oxygen is burned than carbon dioxide released, the air volume decreases.

The physical aspect: the candle heats the air and expands it.

When the oxygen is depleted, the candle goes out and the air cools.

The volume of the air decreases and the water rises..

Why does the water level rise on dipping a spoon?

The water level rises, indicating that spoon occupies space. … The sugar particles being smaller get adjusted between the water molecules. This shows that there are intermolecular space in water.

When we put a drop of blue ink in a glass of water the whole water turns blue after sometime Why?

When we put a drop of blue ink in a glass of water then the particles of ink disperse into the water. This is because ink molecules are small in size as a result they occupy the spaces or gap within the water molecules. Since ink ink molecules are blue in color. Therefore, the water also turns blue after sometime.

When a stone is dipped in a glass containing some water the level of water rises but when a spoon of sugar is added to it and stirred the water level does not rise?

Answer. The water level does not rise because they sugar is a substance that blends in with the water, therefore it doesn’t contain any volume anymore.

What causes the water to rise after the flame goes out?

This is because of the heating of the earth’s surface during the day. The air just above the surface becomes heated and expands. In turn, it begins to rise, since it is lighter, resulting in vertical movement in the atmosphere.

Can a candle stay lit underwater?

With just the open flame above the water’s surface, this process will transform the candle into a hollow tube of wax. … The water surrounding the candle is the secret to this “trick.” It keeps the exterior of the candle at a cool temperature, so the area touching the water never melts.

What happens to the water level when the stone is dipped in water what is the reason?

If stones are removed from the boat, it becomes lighter and displaces less water. That means it rises up so that less of its volume is below the surface. … If something is submerged in water, it will displace an amount of water equal to its volume.

How does the water rise inside the cup?

At first, the flame heats the air inside the container and this hot air expands quickly. Some of the expanding air escapes from under the vase where you might have seen some bubbles. When the flame fades and goes out, the air in the container cools and cooler air contracts or takes up less space.

What happens when an object is placed in water?

Observing an object placed in water helps illustrate now an object’s density influences its buoyancy. All objects, even those that float, displace some water. Specifically, when placed in water, an object sinks into the water until it displaces an amount of water equal to its own mass.

What was removed from the air into the jar to allow space for the water to come in?

Candle wax is a form of hydrocarbon. When it burns, oxygen (from air) reacts with the wax to form two new gases; carbon dioxide and water vapour. Some of the carbon dioxide would dissolve into the water and most of the water vapour would condense back into liquid water.
