What does broad mean in science?

What is the base word of Expand?
Expand is a combination of the Latin words ex-, meaning “out,” and pandere, “to spread.” The idea of spreading out was always there, though the current idea of something actually becoming larger was first recorded in the mid-17th century.
What does expand mean science?
An increase in the volume
Scientific definitions for expansion An increase in the volume of a substance while its mass remains the same. Expansion is usually due to heating. When substances are heated, the molecular bonds between their particles are weakened, and the particles move faster, causing the substance to expand.
What is broadening of meaning?
Broadening of meaning . . . occurs when a word with a specific or limited meaning is widened. The broadening process is technically called generalization.
Is it broad base or broad-based?
involving participation or support by a broad spectrum of things or people: The senator had a broad-based campaign. “Is” it time for a new quiz?
What is expansion in chemistry?
Chemical expansion refers to the spatial dilation of a material that occurs upon changes in its composition. When this dilation is caused by a gradual, iso-structural increase in the lattice parameter with composition, it is related to the composition change by the stoichiometric expansion coefficient.
What is contraction in science?
Contraction. (Science: physiology) a shortening or reduction in size, in connection with muscles contraction implies shortening and/or development of tension. Origin: L. Contractus = drawn together.
What is expanding in biology?
Expand. to become widely opened, spread apart, dilated, distended, or enlarged; as, flowers expand in the spring; metals expand by heat; the heart expands with joy. 1. To lay open by extending; to open wide; to spread out; to diffuse; as, a flower expands its leaves.
What is expanding in physics?
expansion, in physics, increase in volume resulting from an increase in temperature. Contraction is the reverse process. When heat is applied to a body, the rate of vibration and the distances between the molecules composing it are increased and, hence, the space occupied by the body, i.e., its volume, increases.
How do you use broaden?
become broader.
- The party needs to broaden its appeal to voters.
- We have been trying to broaden its commerce with other nations.
- The course helps school-leavers broaden their knowledge of the world of work.
- You should broaden your experience by travelling more.
- She wanted to travel to broaden her horizons.
What is another word for broad based?
generalized, generalised, far-reaching, massive, broad-, wide-scale, all-inclusive, full-scale, broad-scale, inclusive, considerable, across-the-board, pervasive, all-encompassing, wide-spread, multi-sectoral, multisectoral, overarching, overall, sweeping, all-embracing, expansive, largescale, varied, population-based.
What is broad based approach?
A broad-based approach to employee retention simply means your organization engages in business practices that foster good working relationships and a productive, satisfied workforce.
What is expansion and contraction in science?
Substances expand (increase in size) when they get warmer, and they contract (decrease in size) when they get cooler. This property can be useful. For example: Thermometers work because the liquid inside them expands and rises up the tube when it gets hotter.
What is expansion in science class 6?
Expansion: A process in which an object becomes bigger in size, e.g., metals expand on heating. Melting: A process in which a solid melts to become a liquid on heating is called melting.
What is expanding and contracting?
Materials expand or contract when subjected to changes in temperature. Most materials expand when they are heated, and contract when they are cooled.
What is cell expansion in plants?
Plant cell expansion is believed to result from turgor pressure acting as a driving force on a yielding cell wall, where these factors are controlled by the genetic state of individual cells. In a population, however, the interplay of forces between cells will constrain as well as promote cell expansion.
