Firlakuza [10]3 years ago
5 0

Real gases are those, which deviate from ideal behavior.

Answer: Option D

<u>Explanation: </u>

Very tiny particles are present in real gases and occupying finite space by exerting some specific interactions between them. It takes as the reason for why it deviates from its behaviour. There is a lot of difference between a real gas and ideal gas. Ideal gas is the one that which is imaginary, and does not exist. Its characteristics are ideal, and all other real gases, try to follow them.

Real gases, are available in the atmosphere, but need not be naturally available. There is no relation between number of protons and nature.  And, they won’t behave ideally, at any conditions. We calculate the characteristics of a real gas using ideal gas equation, only because it is very difficult to determine their behaviour.

A small space probe of mass 170 kg is launched from a spacecraft near Mars. It travels toward the surface of Mars, where it will
alukav5142 [94]

Answer:

The change  in momentum is  \Delta p =   kg \cdot m/s      

Explanation:

From the question we are told that  

       The mass of the probe is  m = 170 kg

       The location of the prob at time t = 22.9 s is  A  =

       The  momentum at time  t = 22.9 s is  p = < 51000, -7000, 0> kg m/s

        The net force on the probe is  F =  N

Generally the change in momentum is mathematically represented as

              \Delta p = F * \Delta t

The initial time is   22.6 s

 The final time  is  22.9 s

             Substituting values  

           \Delta p =  * (22.9 - 22.6)

            \Delta p =  * (0.3)  

              \Delta p =   kg \cdot m/s

Which of the following processes DOES NOT occur during the convective transfer of heat within a container of air? Group of answe
vovangra [49]

The volume of a warmed part of the air is reduced and its density increases.

Explanation:

In a convective form of heat transfer, the volume of a warmed part of air is not reduced and its density does not increase.

During convection, heat causes the warm part of the air to expand and its volume increases. When volume increases, density is reduced.

  • Convection is a form of heat transfer that involves the actual movement of particles of the medium.
  • It usually occurs in fluids i.e gases and liquids.
  • In convection, the cold part exerts a buoyant force on the warmer air below and causes it to rise.
  • As the warmer part is rising the cooler part replaces it and a convective cell is formed in the process.

What is the change in electric potential energy when the dipole moment of a molecule changes its orientation with respect to e⃗
AleksandrR [38]

Electric potential energy of a dipole is given as

U = - P.E

U = - PE cos\theta

so change in the potential energy is given by

U_f - U_i = (-PEcos\theta_2)- (-PEcos\theta_1)

\Delta U = PE (cos\theta_1 - cos\theta_2)

here initially it was parallel to electric field while finally it is perpendicular to the electric field

so we have

\Delta U = PE(cos 0 - cos 90)

\Delta U = PE

so above is the change in potential energy of dipole
