Choose the correct answer
(It's impossible for a heat engine 1 point
to produce net work in a
complete cycle if it exchanges
heat only with bodies at a single
fixed temperature). this
statement refer to:
2nd law of thermodynamics
Zeroth law of thermodynamics
1st law of thermodynamics
Gibss Dalton law
(The internal energy of a perfect 1 point
gas is function of the absolute
temperature only) this statement
refer to:
Zeroth law of thermodynamics
Joule law
Dalton law
First Law of thermodynamics
When a liquid is heated at any
one constant pressure there is
one fixed temperature at which
bubbles of vapour form in the
liquid, this phenomenon is known
as:
1 point
Heating
Boiling
Saturation
Mixing
0.05 kg of Steam contained in a 1 point
rigid vessel of volume 0.00755
m3 with a pressure 20 bar. The
temperature of steam will be:
350 °C
425 °C
○ 400 °C
375 °C
Energy has different forms which 1 point
include:
None of the mentioned
All of the mentioned
Work
○ Heat
When two systems have equality 1 point
of temperature witha third
system, they in turn have equality
of temperature with each other.
