Water is composed of what two elements?
-
Oxygen and nitrogen
-
Hydrogen and electrons
-
Protons and neutrons
-
Oxygen and hydrogen
Correct Answer
A. Oxygen and hydrogenExplanation
Water is composed of oxygen and hydrogen. This is because water is a compound made up of two hydrogen atoms bonded to one oxygen atom. The chemical formula for water is H2O, indicating that there are two hydrogen atoms and one oxygen atom in each water molecule. Oxygen and hydrogen are the elements that make up water, and their combination creates the unique properties and characteristics of this essential substance.Rate this question:

A bug is able to walk on water due to water's ____.
-
Specific heat
-
Surface tension
-
Capillary action
-
Polarity
Correct Answer
A. Surface tensionExplanation
Surface tension is the property of a liquid that allows it to resist external forces and form a "skin" on its surface. This skin-like surface tension is created by the cohesive forces between the water molecules. When a bug walks on water, it is able to distribute its weight over a larger area, effectively breaking the surface tension and allowing it to stay afloat. Therefore, surface tension is the reason why bugs are able to walk on water.Rate this question:

Water is transported in plant tissues against gravity due to which of the following properties?
-
Polarity
-
Specific heat
-
Capillary action
-
Surface tension
Correct Answer
A. Capillary actionExplanation
Water is transported in plant tissues against gravity due to capillary action. Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of external forces like gravity. This is possible because of the cohesive forces between water molecules, which allow them to "stick" together and move upwards through narrow tubes or spaces, such as the xylem vessels in plants. This property enables water to move from the roots to the leaves of a plant, providing essential nutrients and moisture for its survival.Rate this question:

Water falling from the sky in the form of a rain drop because of what?
-
Adhesion
-
Cohesion
-
Surface tension
-
Polarity
Correct Answer
A. CohesionExplanation
Cohesion refers to the attraction between molecules of the same substance. In the case of water, the cohesive forces between water molecules are strong, causing them to stick together. This allows water to form droplets and fall from the sky as rain. The cohesive forces overcome gravity, enabling the water droplets to maintain their shape and size as they descend. Therefore, cohesion is the reason for water falling from the sky in the form of raindrops.Rate this question:
