Question

What best describes the burning of a house from a thermo dynamical standpoint?1. ∆H < 0, ∆S < 0 2. ∆H < 0, ∆S > 0 3. ∆H > 0, ∆S > 0 4. ∆H > 0, ∆S < 0

Answer 1

Answer:

3. ∆H > 0, ∆S > 0

Explanation:

In terms of change in heat, the final heat is greater than the initial heat. Hence;

∆H > 0

Also, in a burning house there would be an increased level of disorderliness; entropy. So we have;

∆S > 0

This means that we have;

∆H > 0, ∆S > 0

The correct option is 3.
