Explanation:

A hard is identified as having a definite shape and also definite volume. A fluid is characterized as having a definite volume, but not a identify shape. A gas is defined as neither having a definite form nor a definite volume.

You are watching: Why do solids have a definite shape


Explanation:

Solids are identified as having definite shapes and volumes. The atoms in a hard touch one another and are addressed in strict positions. Unlike liquids or gases, molecules inside a solid room not maybe to openly move previous one another. Solids will certainly retain their shape also when placed in open atmospheres.


Explanation:

Aluminum is no a high-density metal. Friend may figure this the end by compare aluminum"s thickness (2.7 g/mL) come the thickness of various other metals. Aluminum is very lightweight contrasted to other metals, do it ideal for the building and construction of things favor airplanes.

Aluminum is a an excellent conductor that heat and electricity. The is ductile, an interpretation it have the right to be turned into wire, and it is malleable, meaning it have the right to be made right into sheets.


Explanation:

A crystalline heavy is made up of a repeating pattern of atoms dubbed a decision lattice. Atom moving around randomly, and also taking the form of your container are descriptions of fluids (liquids and gasses).


Explanation:

Dissolving a solute in a solvent boosts the variety of dissolved particles per mass of solvent. Freezing suggest depression is a colligative property of solutions, and will decrease together the molality that the equipment increases. Boiling point and osmotic pressure increase as the molality that the solution increases. Temperature is unaffected through the dissolved of solutes in a solvent.


Correct answer:

The salt lowers the freezing point of the ice, do it much easier to clear or navigate safely


Explanation:

The salt to reduce the freezing suggest of the water. Upon enhancement of salt to icy roads and also sidewalks, the ice melts, making it much safer to drive and also walk. Freezing allude depression is a colligative property and also depends ~ above the number of dissolved particles, no the form of particles. Thus, sugar would also decrease the freezing allude of ice. The amount the freezing allude decreases is proportional to the variety of dissolved solutes in the solution.


Explanation:

Crystals, or crystalline solids consist of repeated, consistent pattern the atoms recognized as a decision lattice. Amorphous solids carry out not have actually a lattice, and also consist of a fixed of atoms without a repeated pattern.


Explanation:

Solids have well identified shapes because their atom are hosted tightly together, only allowing localized movement. Since a solid"s atoms room so close together, solids space incompressible. Over there so tiny space between atoms that they can"t get any type of closer together. The factor a solid"s atoms are so close with each other is lock experience strong intermolecular forces, leading to high stability. Solids can either be crystalline or amorphous in structure. Crystalline structure is regimented and grid-like, if amorphous has actually no regular, repeating sample of atoms.

Example question #9 : Solids and also Liquids


Which step of matter has actually a identify volume, but no identify shape?


Possible Answers:

All phases have actually these qualities


Gas


Liquid


Solid


Correct answer:

Liquid


Explanation:

Liquids have actually a few similar properties to solids. They room not conveniently compressible and also they have a definite continuous volume. Unlike solids, however, liquids execute not have a definite shape and also conform come the framework that consists of them. Solids maintain a consistent shape.

Gases have no definite form or volume.

Example concern #10 : Solids and also Liquids


What is the freezing suggest of three moles the HCl liquified into 1kg of water?

*

*


Possible Answers:

*


*



*


*


Correct answer:


Explanation:

Freezing point depression describes the phenomenon the occurs as soon as the freezing suggest of a systems is decreased due to the existence of ions or molecules. The freezing allude depression is offered by the formula:

*

*
 refers come the van"t Hoff factor, i beg your pardon is the number of ions produced by dissolving a solitary molecule the the solute. In this case, the van"t Hoff element is two due to the fact that HCl will create two ions per molecule in solution.

*
 referes to the molality, which is the mole of solute every kilogram of solvent. We can rewrite our equation in these terms:

*

We know every one of these terms, enabling us come solve:

*

This tells us that the freezing point of the systems is 11.16 degrees less than the freezing suggest of pure water.
