The following statement is true only under some specific conditions. Write the conditions for the following statement in not more than two sentences. The heat energy q absorbed by a gas is `DeltaH`.

Text Solution

AI Generated Solution

To determine the conditions under which the statement "the heat energy \( q \) absorbed by a gas is \( \Delta H \)" is true, we need to consider the nature of the process involved. The statement holds true specifically when the process occurs at constant pressure (isobaric conditions). Under these conditions, the heat absorbed by the gas is equal to the change in enthalpy (\( \Delta H \)), which is defined as \( \Delta H = \Delta U + P \Delta V \). ### Step-by-Step Solution: 1. **Identify the Concept**: Understand that the statement relates to the relationship between heat absorbed and enthalpy change. 2. **Recall the Definition of Enthalpy**: Enthalpy change (\( \Delta H \)) is defined as the sum of the internal energy change (\( \Delta U \)) and the work done by the system at constant pressure (\( P \Delta V \)). ...
