When the ionic compound NaBr dissolves in water Br ions are pulled into solution by the attraction between what two particles?
When NaBr dissolves in water, Br ions are pulled into solution by the attraction between the polar water molecules (with their partially negative oxygen atoms) and the positively charged sodium ions in the lattice of NaBr. The water molecules surround the Br ions, breaking the ionic bonds and allowing the ions to move freely in the solution.
What phases are in equilibrium at a substance's melting point?
Evaporating and condensing
A cathode ray produced in a gas-filled tube is deflected by a magnetic field A wire carrying an electric current can be pulled by a magnetic field A cathode ray is deflected away from a negatively?
A cathode ray in a gas-filled tube is deflected by a magnetic field due to the Lorentz force acting on the charged particles in the ray. A wire carrying an electric current can be pulled by a magnetic field through the interaction of the magnetic field and the moving charges in the wire. A cathode ray is deflected away from a negatively charged object due to the repulsion between the negatively charged object and the negatively charged particles in the cathode ray.
What compound machine is a zipper?
A zipper is a compound machine that functions as a series of simple machines working together. It typically consists of two flat metal pieces with interlocking teeth that are pulled together and apart by a slide mechanism. The teeth act as inclined planes that wedge together when the slider is moved up, and apart when moved down, allowing the zipper to open and close.
Why organic compounds have low melting and bioling points?
Organic compounds generally are long hydrocarbon chains which are only attracted to each other by Van der Waals bonds which are the weakest intermolecular bonds. Since the bonds between molecules are weaker, they tend to melt much more quickly then stronger intermolecular bonded molecules.
How solid act like a liquid?
Surface tension-Attractive forces cause particles on the surface of a liquid to pull together and resist from being pushed apart. These particles on the surface are pulled toward the center of the liquid and and sideways along the surface. There are no liquid particles above to pull on them. Particles under the surface are pulled in all different directions. Surface tension is the uneven forces acting on the surface particles of a liquid. Surface tension causes a liquid to act like it has a thin film stretched across the surface.
What force pulled the particles of gas and dust together making the solar nebular shrink?
Gravitational force pulled the particles of gas and dust together, causing the solar nebula to shrink and eventually form the solar system.
If atoms energy during a change of state they are pulled together by attractive forces and become more organized.?
During a change of state, the atoms or molecules typically experience an increase in energy which allows them to overcome the attractive forces that hold them together in their current state. This increased energy allows the particles to transition to a new state with greater disorder or randomness.
What force caused a ball of dust rock and ice to be pulled together to form earth?
The force of gravity caused the various particles of dust, rock, and ice to be pulled together to form Earth. Over time, the gravitational attraction between these particles caused them to collide and merge, eventually forming a larger body that became our planet.
What do two things do when there is a pair of forces pulling them together?
When two things are being pulled together by a pair of forces, they move towards each other. The direction of their movement depends on the magnitude and direction of the forces involved. If the forces are equal and opposite, the objects will remain stationary.
What fundamental forces pulled together hot dense areas of matter in the early Universe to begin the process of star formation?
gravity
What forces are combinations of pushing and pulling forces?
Tension and compression forces are combinations of pushing and pulling forces. Tension forces occur when an object is being pulled apart, while compression forces occur when an object is being pushed together. Both forces act along the length of an object, causing it to either stretch or compress.
What is a region in which charged particles can be pushed or pulled?
An electric field is a region in which charged particles can be pushed or pulled due to the presence of other charged particles. The strength of the electric field determines the force experienced by charged particles within the region.
What king of force objects are pulled toward one another in an atom?
In an atom, objects are pulled toward each other by electromagnetic forces between charged particles such as protons and electrons. These forces are responsible for the attraction between the positively charged nucleus and the negatively charged electrons, keeping the atom stable.
Is the moon pulled by the earth's gravity?
Yes. the mutually attracting forces of gravity hold the moon and earth together and cause the earth's tidal forces.
Where did the stars come from?
When the big bang occurred tiny particles spread out evenly through the universe. Wel almost evenly and due to these tiny flaws in the spreading. Gravity pulled these particles together and after enough of these particles form. Hydrogen atoms begin to fuse creating stars that shine.
What is the force called when something is stretched?
its called the push of the decaltill force xx
