Air at 25°C and 5 atm is throttled by a valve to 1 atm. If the valve is adiabatic and the change in kinetic energy is negligible
Vsevolod [243]

Answer:

T_{2} = 25^{\circ}C

Solution:

As per the question:

Temperature, T_{1} = 25^{\circ}C

Pressure, P_{1} = 5 atm[\tex]Now,We know that the process of throttling occurs in adiabatic conditions where no heat is transferred in between the system and the surrounding, i.e., Q = 0Thus no work is done in this process, i.e., W = 0Enthalpy also remains same from one state to the other state, i.e., [tex]\Delta h = 0

Therefore, from the eqn:

Q - W = \Delta h + \Delta KE

We can write:

\Delta h = h_{1} - h_{2} = 0

\Delta h = C_{p}\Delta T

C_{p}(T_{2} - T_{1}) = 0

Thus

T_{1} = T_{2} = 25^{\circ}C

where

T_{2} = Exit temperature

Charged particles posses a region of influence also called a (an)
Delvig [45]

Answer:(c)

Explanation:

Charge particle posses a region of influence called a filed i.e. Electric field.

It is a region around the charged particle such that other charge particle experiences force due to this field. The nature of force is decided by the charge on the particle creating an electric field.

For a positive charge, electric field lines emerge out of it, and for a negative charge, it acts as radially inwards.
