15 15 definitions of words related to our chemistry unit terms
Hello and welcome to my chemistry glossary. This is for an activity my group is doing since we can't do a normal text because of quarantine. I hope I get a good grade :) [Sorry it's not in alphabetical order, some words came late]
Astrochemistry
Noun
The study of the chemical substances and species occurring in stars and interstellar space.
Example: "I need to study for the astrochemistry text tomorrow."
pt_br: Astroquímica
Boiling point
Noun
A certain temperature that when reached, the substance (liquid) will start turning into gas.
Example: The water's boiling point is at 100 degrees Celsius."
pt_br: Ponto de ebulição
Change
Noun
"The act or instance of making or becoming different."
Example: "The schedule will change tomorrow."
pt_br: Mudança
Chemical property
Noun
"A property or characteristic of a substance that is observed during a reaction in which the chemical composition or identity of the substance is changed."
Example: "One of the water's chemical properties is that it is a natural solvent."
pt_br: Propriedade química
Chemistry
Noun
The science that deals with the properties, composition, and structure of substances, the transformations they undergo, and the energy that is released or absorbed during these processes.
Example: "Chemistry is the subject I like the most."
pt_br: Química
Color
Noun
The quality of an object or substance with respect to light reflected by the object, usually determined visually by measurement of hue, saturation, and brightness of the reflected light; saturation or chroma.
Example: "Black is my favorite color."
pt_br: Cor
Combustible
Adjetive
Something that can be burned easily.
Example: "Gasoline is a combustible substance, so be careful with fire around it."
pt_br: Combustível
Composition
Noun
The way in which the parts of something are arranged.
Example: "We cannot determine the chemical composition of soil simply by touching it."
pt_br: Composição
Conductivity
Noun
The property or power of conducting heat, electricity, or sound.
Example: "In every case there was a loss of conductivity, and usually in a degree proportioned to the atomic weight of the added ingredient."
pt_br: Conductividade
Density
Noun
The degree of compactness of a substance.
Example: " The density of this substance is very big."
pt_br: Densidade
Hardness
Noun
The quality or condition of being hard.
Example: "This substance has high hardness level."
pt_br: Dureza
Melting point
Noun
A certain temperature that when reached, the substance will start turning into liquid.
Example: "The ice's melting point is at 0 degrees Celsius."
pt_br: Ponto de fusão
Physical property
Noun
A property (as color, hardness, boiling point) of matter not involving in its manifestation a chemical change.
Example: "The components of the sample will then distribute themselves according to their relative affinities for the stationary phase, and are then recorded and quantified by measuring a physical property."
pt_br: Propriedade física
Planet
Noun
A celestial body distinguished from the fixed stars by having an apparent motion of its own (including the moon and sun), especially with reference to its supposed influence on people and events.
Example: "Earth is the third planet closest to the Sun."
pt_br: Planeta
