Test: Matter In Our Surroundings (Medium)

As Meena pushes the bottle, the water level in the bottle increases and air present in the bottle gets pushed into the tube, which is bubbled out from the beaker. This experiment proves that air and water occupy some space, and only one matter can occupy space at any time.

The fraction of solute present in water as temperature concentration in water will decrease; hence, the fraction of solute present in water changes.

The matter is affected by the inertia. Inertia is the tendency of the matter to be in a state of rest or motion. Example: The book on the desk remains in rest position utilities picked up from the desk. Thus It Is Showing Inertia.

The water kept in an earthen pot main cool even in summer because of the earthen pot as many small holes. Water seeps out through them and evaporates from the surface of the pot. The energy needed for evaporation is taken from the water kept in the earthen pot. As a result, water kept in earthen pot become cool.

If the tube has been open on both sides, the mercury will fall, so that is not the case. Also, the pressure will increase slightly because of the weight of mercury. So the tube must be closed at both the ends.

On the increasing temperature, the diffusion rate increases as the kinetic energy of matter increases and more intermixing of matter occurs.

When Venu blows the straw, he applies pressure by pushing air into which form air bubbles water, the pressure in the basin increases and the water level in the beaker increases.The air bubbles formed in the water escape into the beaker.

A volatile liquid one that evaporates or evaporates quickly at room temperature. Volatile Liquids Have a low boiling point. As a result, they evaporate very easily at room temperature.
