Answer #1

1) Negative kelvin temperature scale temperature is not possible
ti measure (Absolute zero=273 K (or) 0K)...(**b** is
correct)

2)Temperature is the intensive property (**C** is
correct)

3)**Insulated system** can not exchange maatter and
energy between system and surroundings.

4)A system is said to be in mechanical equilibrium if there is no force between system and surroundings,Therefore

**none of given** is correct.

5)Toal energy is the sum of Kinetic energy, potential energy
(or) internal energy. Therefore **none of given** is
correct.

6) The mode of heat transfer through a solid wall is
**conduction.**

7)**Kinetic energy** is component of macroscopic
energy.

A block is attached to a spring, with spring constant k, which
is attached to a wall. It is initially moved to the left a distance
d (at point A) and then released from rest, where the block
undergoes harmonic motion. The floor is frictionless.
The points labelled A and C are the turning points for the
block, and point B is the equilibrium point.
1)
Which of these quantities are conserved for the spring and block
system (Select all...

We consider an isolated system made up of 2 moles of an ideal
gas which can pass reversibly from a state A (PA, VA, TA = 300 K)
to a state B (PB = 3PA, VB = VA / 3, TB) by a transformation which
comprises two stages: it is first isochoric (constant volume), then
isobaric (constant pressure).
1-Determine the work involved.
The ideal gas constant is R = 8.31 J / K.mol, and the internal
energy of an ideal...

A rigid copper tank, initially containing 1 m3 of air at 295 K,
4 bar, is connected by a valve to a large supply line carrying air
at 295 K, 15 bar. The valve is opened only as long as required to
fill the tank with air to a pressure of 15 bar. Finally, the air in
the tank is at 310 K. The copper tank, which has a mass of 20 kg,
is at the same temperature as the...

It is possible to go from a given initial equilibrium state of a
system to a given final equilibrium state by a number of different
paths, involving different intermediate states and different
amounts of heat and work. Since the internal energy of a system is
a state function, its change between any two states must be
independent of the path chosen. The heat and work flows are,
however, path-dependent quantities and can differ on different
paths between given initial and...
