Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion : The isothermal curves intersect each other at a certain point.
Reason : The isothermal change takes place slowly, so the isothermal curves have very little slope.
Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion : We can not change the temperature of a body without giving (or taking) heat to (or from) it.
Reason : According to principle of conservation of energy, total energy of a system should remains conserved.
Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion : The specific heat of a gas is an adiabatic process is zero and in an isothermal process is infinite.
Reason : Specific heat of a gas in directly proportional to change of heat in system and inversely proportional to change in temperature.
Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion : The heat supplied to a system is always equal to the increase in its internal energy.
Reason : When a system changes from one thermal equilibrium to another, some heat is absorbed by it.
Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion : A room can be cooled by opening the door of a refrigerator in a closed room.
Reason : Heat flows from lower temperature (refrigerator) to higher temperature (room).
Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion : If an electric fan be switched on in a closed room, the air of the room will be cooled.
Reason : Fan air decrease the temperature of the room.
Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion : The internal energy of an isothermal process does not change.
Reason : The internal energy of a system depends only on pressure of the system.
Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion : An adiabatic process is an isentropic process.
Reason : Change in entropy is zero in case of adiabatic process.
