rises because the water expands when heated, causing an increase in volume which leads to a higher level in the tube.


How can a half test tube of sugar and a half test tube of water add up to one full test tube?

When sugar dissolves in water, it occupies space within the water molecules, leading to an increase in volume. So, if you dissolve a half test tube of sugar into a half test tube of water, the volume of the mixture will be greater than the sum of the individual volumes of sugar and water, resulting in a full test tube.


Does liquid water rise higher in a narrow tube or a wide tube?

Rise or fall of liquid in a small passage or tube. When a glass tube of small internal diameter is inserted into water, the surface water molecules are attracted to the glass and the water level in the tube rises. The narrower the tube, the higher the water rises. The water is said to "wet" the tube. Water will also be drawn into the fibres of a towel, even if the towel is in a horizontal position. Conversely, if a glass tube is inserted into mercury, the level of the liquid in the tube falls. The mercury does not wet the tube. Capillarity is caused by the difference in attraction of the liquid molecules to each other and the attraction of the liquid molecules to those of the tube.


Why does the water rise in the measuring tube when you use hydrogen gas?

When hydrogen gas is produced in a chemical reaction, it displaces the water in the measuring tube since hydrogen is less dense than water. As a result, the water level in the tube rises as the lighter hydrogen gas occupies the space previously filled by water.


What liquid is in the upper part of the test tube when you mix water and oil?
