Interpretation:
For an open system in which air is considered as ideal gas is expanding in a home due to heating of air at constant pressure resulting in leakage of air at outdoors, the expression which relate household temperature with time should be derived.
Concept Introduction:
For an open system the mass and energy can exchange from the surrounding, the mass balance is therefore,
In terms of moles or material balance is
The energy balance for open system is:
And
And for ideal gas
