Which of the following is a FALSE statement? O Heat is energy transferred into or out of a system as a result of a temperature difference between the system and its surroundings. O The heat added to an ideal gas during the transition from state 1 to state 2 depends only on the initial and final states, 1 and 2, and not on the path by which the gas went from one to the other. When a gas goes from one state to another, the work done depends on the path followed. It does not make sense to refer to "the amount of heat in a body." When an ideal gas experiences a free expansion, its temperature doesn't change.

Expert Solution
Step 1

First statement is correct as heat is transferred always due to temperature difference.Heat is transferred from system at high temperature to system at low temperature.

Second statement is false as amount of heat needed to go from state 1 to another state is path dependent.

 

Third statement is correct because work done is also path dependent  like amount of heat while transition of state.

 

Fourth statement is correct as the heat is defined as the flow of energy from a body at higher temperature to a cooler body.

 

Fifth statement is correct as there is no change in internal energy during a free expansion in which gas expands into a vacuum, So the temperature remains the same
