Ductility: Able to undergo change of form without breaking

·Malleability: capable of being shaped, as by Hammering or pressing:

·Density (give an Example): a measurement of how Tightly matter is crammed together. Example: Oil floats on vinegar because Its density is less.

  • Chemical properties of matter (give an Example): Are any of the properties Of matter that may only be observed and measured by performing a chemical change or chemical Reaction. Example: oxidation states

·What is a physical Change (give an example): A usually reversible change in the physical 

properties of a substance,as size or shape. Example: When melting an ice cube.

·Difference between Chemical properties and physical properties (give an example): A physical property is an aspect of Matter that can be observed or measured without changing it. Examples of physical properties include color, Molecular weight and volume. A chemical property may only be Observed by changing the chemical identity of a Substance. This property measures the potential for undergoing a chemical changeExamples of chemical properties include Reactivity, flammability and oxidation states.

·Two kinds of solids (give an example): crystalline solids And amorphous solids. Examples: Crystalline: sugar and diamond. Amorphous: Glass and plastic

·Surface tension: Surface tension is the elastic tendency of a fluid surface which makes it acquire the least surface area possible. Surface tension allows insects (e.G. water striders), usually denser than water, to float and stride on a water surface.

·Viscosity: the property of a fluid that resists the force tending

 to cause thefluid to flow

·Why is the Behavior Of Gases different from solids or liquids?: Because gases particles move super fast and that why gas is created and Are all spread out and very separated and solids and liquids particles are very Joint specially the solids particles.

·What are the 3 Factors that affect behavior of gases and describe each one of them: pressure, temperature, and volume. Pressure: An increase in pressure increases solubility, whereas a decrease in pressure Decreases solubility. This statement is formalized in Henry's Law, which states that the solubility of a Gas in a liquid is directly proportional to the pressure of that gas above the Surface of the solution. Temperature: As the temperature is Increased, the gas becomes more "ideal" and the same is true if the Pressure is decreased/volume increased. Volume: The volume of gas increases Proportionally to absolute temperature and decreases inversely proportionally To pressure. Since a gas fills any container in which it is placed, volume is An extensive property, which means properties that depend on the amount of gas.
