What happens to these physical properties as the strength of intermolecular forces increases?

Physics
1 answer:
Setler [38]3 years ago
4 0

Answer: The Boiling point,melting point, surface tension and viscousity will increase while the Vapor pressure will decrease.

Explanation:An increase in the strength of intermolecular forces increases will lead to an increase in force applied to break the barriers posed by the strength of the molecules.

This increased intermolecular strength will cause a rise in boiling point,melting point, viscousity and surface tension.

The Vapor pressure reduces with increasing intermolecular strength. Vapor pressure is the amount of vapor that is equilibrium with its own liquid or solid. Hence,with increasing intermolecular strength the amount of vapor that is in equilibrium with its own liquid will reduce.

FromTheMoon [43]

The given question is incomplete. The complete question is as follows.

An oxygen molecule is adsorbed onto a small patch of the surface of a catalyst. It's known that the molecule is adsorbed on 1 of 36 possible sites for adsorption. Calculate the entropy of this system.

Explanation:

It is known that Boltzmann formula of entropy is as follows.

             s = k ln W

where,   k = Boltzmann constant

              W = number of energetically equivalent possible microstates or configuration of the system

In the given case, W = 36. Now, we will put the given values into the above formula as follows.

                  s = k ln W

                    = 1.38 \times 10^{-23} ln (36)        

                    = 4.945 \times 10^{-23} J/K

Thus, we can conclude that the entropy of this system is 4.945 \times 10^{-23} J/K.

What is the mechanism of hydraulic machine ​
nata0808 [166]

Answer:

The hydraulic press allows the applied force (F1) to be converted into a higher force (F2) along some path as many times as the surface of the driven hydraulic cylinder (A2) is larger than the surface of the driving hydraulic cylinder (A1). The hydraulic press works on the basis of Pascal's law, which reads: External pressure is transmitted through the fluids equally in all directions.

A 12.0-g cd with a radius of 5.81 cm rotates with an angular speed of 33.2 rad/s. what is its kinetic energy?
schepotkina [342]
Use the formula 1/2*I*w^2 where w is the angular speed and I is the rotaional inirtia (for disk it is .5*mass*radius^2).

Use F = 1/T as your basis:
skelet666 [1.2K]
  • Time Period=T=2.5×10^{-3}s

Now

Frequency:-

\\ \rm\rightarrowtail \nu=\dfrac{1}{T}

\\ \rm\rightarrowtail \nu=\dfrac{1}{2.5\times 10^{-3}}

\\ \rm\rightarrowtail \nu=0.4\times 10^{3}

\\ \rm\rightarrowtail \nu=400Hz
