- Tea kept in a thermos flask is vigorously shaken. If the tea is considered as a system, then its temperature will
- Which of the following is an extensive property of a system?
- The expression for entropy change, ΔS = n Cp . ln (T₂/T₁), is valid for the __________ of a substance.
- When a system in equilibrium is subjected to a change in temperature, pressure or concentration, the equilibrium is displaced in a direction which tends to undo the effect of the change. This is called the
