Answer:
An applied force is an interaction of one object on another that causes the second object to change its velocity. A resistive force passively resists motion and works in a direction opposite to that motion. An inertial force resists a change in velocity.
Explanation:
Answer:
<u>The deviations are :</u>
- <u>The activation energy which changes with temperature</u>
- <u>The arrhenius constant which depends on the temperature</u>
Explanation:
- There are deviations from the Arrhenius law during the glass transition in all classes of glass-forming matter.
- The Arrhenius law predicts that the motion of the structural units (atoms, molecules, ions, etc.) should slow down at a slower rate through the glass transition than is experimentally observed.
- In other words, the structural units slow down at a faster rate than is predicted by the Arrhenius law.
- <em>This observation is made reasonable assuming that the units must overcome an energy barrier by means of a thermal activation energy. </em>
- The thermal energy must be high enough to allow for translational motion of the units <em>which leads to viscous flow of the material.</em>
- Both the Arrhenius activation energy and the rate constant k are experimentally determined, and represent macroscopic reaction-specific parameters <em>that are not simply related to threshold energies and the success of individual collisions at the molecular level. </em>
- Consider a particular collision (an elementary reaction) between molecules A and B. The collision angle, the relative translational energy, the internal (particularly vibrational) energy will all determine the chance that the collision will produce a product molecule AB.
- Macroscopic measurements of E(activation energy) and k(rate constant ) <em>are the result of many individual collisions with differing collision parameters. </em><em>They are averaged out to a macroscopic quantity.</em>
They have a low boiling point because of weak intermolecular forces. They
Explanation:
Covalent compounds are compounds that are known to have weak intermolecular forces and hence low boiling point.
Covalent bonds are bond formed between two or more atoms having zero or very small electronegativity difference. Such bonds exists between molecules of non-metals.
Here are some properties of covalent bonds;
- They are gases or volatile liquids or low melting point solids
- Most of them are insoluble in polar solvents or water but they are generally soluble in non-polar organic solvents.
- They are mainly non-conductors.
