For a given heat in liquid, the apparent expansion is more than that of real expansion
FALSE (The real expansion is more (or) less than that of apparent expansion)
Thermal energy always flows from a system at higher temperature to a system at lower temperature.
TRUE
According to Charless law, at constant pressure, the temperature is inversely proportional to volume.
FALSE (Volume is directly proportional to temperature at constant pressure.)
(A): There is no effects on other end when one end of the rod is only heated... (R): Heat always flows from a region of lower temperature to higher temperature of the rod.
(c) Assertion is true, but the reason is false.
(A): Gas is highly compressible than solid and liquid.. (R): Interatomic or intermolecular distance in the gas is comparably high
(a) Both the assertion and the reason are true and the reason is the correct explanation of assertion.
