The properties of matter include any traits that can be measured, such as an object’s density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature, and more. A block of ice changes its physical properties as it melts, but chemically it is the same water in either state.

The amount of matter in a substance is its mass. In order to calculate the amount of matter in a given volume of a sample, you will use the density equation: density = mass/volume. To find mass using the density equation, you must know the volume of your sample and its density.

7 physical properties of matter

• Volume. Definition.
• Boiling point. Definition.
• Odor. Definition.
• Melting point. Definition.
• Color. Definition.
• Density. Definition.
• Texture. Definition.

The three basic properties of matter are volume, mass, and shape. 2. All matter is made up of tiny particles called atoms.

Examples of physical properties of matter include melting point, color, hardness, state of matter, odor, and boiling point.

A change in size or shape is a physical change. 16. A chemical change means a new substance with new properties was formed. When milk turns sour, this is a physical change because a change in odor does not indicate a chemical change.

A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.

A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.

Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties.

Sometimes it can be tricky to know whether or not a chemical reaction has occurred. For example, when you melt ice into water, you can write the process in terms of a chemical reaction. However, the chemical formula on both sides of the reaction is the same. Thus melting point is a physical property.

Properties that can be determined without changing the composition of a substance are referred to as physical properties. Characteristics such as melting point, boiling point, density, solubility, color, odor, etc. are physical properties.

The explosion of fireworks is an example of chemical change. During a chemical change, substances are changed into different substances. Another words, the composition of the substance changes.

The formation of black ice is neither a chemical change nor a physical change.

The catastrophic rupture of a pressurized gas/vapor-filled vessel by means other than reaction, or the sudden phase-change from liquid to vapor of a superheated liquid.

Explosive shock waves can cause situations such as body displacement (i.e., people being thrown through the air), dismemberment, internal bleeding and ruptured eardrums. Shock waves produced by explosive events have two distinct components, the positive and negative wave.

In space no one can hear you explode… Many astronomical objects such as novae, supernovae and black hole mergers are known to catastrophically ‘explode’. But as long as the explosion doesn’t require oxygen, then it will work in much the same way in space as on Earth.

An explosion is a rapid expansion in volume associated with an extremely vigorous outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Supersonic explosions created by high explosives are known as detonations and travel via shock waves.

C-4 is composed of explosives, plastic binder, plasticizer to make it malleable, and usually a marker or odorizing taggant chemical. C-4 has a texture similar to modelling clay and can be molded into any desired shape. C-4 is metastable and can be exploded only by the shock wave from a detonator or blasting cap.

One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.

The following factors must be present simultaneously for an explosion to occur:

• A flammable material in the production process or surroundings.
• Oxygen (air)
• Ignition source.
• A particular ratio between oxygen and flammable material.

So, why doesn’t sugar explode or at least light on fire when we eat it? When we eat sugar, the process is different because it happens within cells in our body and is con- trolled by large molecules called enzymes. This reaction occurs at a slower rate and the energy is stored, so no explosion occurs.
