What are two quantitative physical properties?
Quantitative physical properties are measured and include temperature, height, and mass. A physical change is a change in which the composition of the substance remains unaltered and no new substances are produced. Examples of physical change are a change of size or shape, a change of state, and dissolving. 2.
What are the 3 main physical properties of water?
Physical properties of water are related to the appearance of water, namely, the color, temperature, turbidity, taste, and odor.
What are some physical properties of water?
Physical properties
| Selected physical properties of water | |
|---|---|
| melting point | 0.00 °C |
| boiling point | 100.00 °C |
| maximum density (at 3.98 °C) | 1.0000 grams per cubic centimetre |
| density (25 °C) | 0.99701 grams per cubic centimetre |
What are two intensive physical properties of water?
The water must reach 100 degrees Celsius in order for the water to start boiling. So the boiling point is an intensive property. Likewise, melting point is also an intensive property. Other examples of intensive properties include density , solubility, color, luster, freezing point and malleability.
What are 3 examples of quantitative properties?
Two grams mass, three coulombs charge, five inches long – these are examples of quantitative properties.
Does water have physical and chemical properties?
Water has a very strong hydrating tendency due to its dielectric constant. It dissolves many ionic compounds….Hydrolysis reaction.

What is the physical and chemical property of water?
Water, also known as H2O, is a substance composed of the chemical elements hydrogen (H2) and oxygen (O2). As the polar inorganic compound, water is a colorless, tasteless and odorless liquid. Water being the most studied chemical compound, is known as the universal solvent.
Why is the concentration of a solution different at different temperatures?
When expressed as molarity, the concentration of a solution with identical numbers of solute and solvent species will be different at different temperatures, due to the contraction/expansion of the solution.
Can a physical property be observed without a physical change?
We can observe some physical properties, such as density and color, without changing the physical state of the matter observed. Other physical properties, such as the melting temperature of iron or the freezing temperature of water, can only be observed as matter undergoes a physical change.
Why is the rate of condensation unaffected by the presence of solute?
Since the rate of condensation is unaffected by the presence of solute, the net result is that the vaporization-condensation equilibrium is achieved with fewer solvent molecules in the vapor phase (i.e., at a lower vapor pressure) ( Figure 1 ).
How does the boiling point of a solvent change?
The extent to which the vapor pressure of a solvent is lowered and the boiling point is elevated depends on the total number of solute particles present in a given amount of solvent, not on the mass or size or chemical identities of the particles.
