Question

Three objects. A at 30° C, B at 303 K and C at 420 K are in thermal contact. Then ans were
following questions.
(1) Which are in " Thermal equlibrium" among A, B and C..
(ii) From which object to another heat is transferred.​

Answer 1

Answer:

1)A AND B ARE AT THERMAL EQUILLIBRIUM.

2)FROM C HEAT IS TRANSFERRED TO A AND B(BECAUSE C HAS MORE TEMPERATURE).

Answer 2

(1) A and B are in Thermal equilibrium.

Two actual frameworks are in thermal equilibrium assuming that there is no net progression of nuclear power between them when they are associated by a way porous to warm. Warm balance submits to the zeroth law of thermodynamics. A framework is supposed to be in warm balance with itself assuming the temperature inside the framework is spatially uniform and transiently steady. Frameworks in thermodynamic harmony are generally in warm balance, however, the opposite isn't correct all the time.

(2) From C, heat is transferred to A and B (This is because C has a higher temperature).
