(1). A liquid evaporates to vapour
(2). Temperature of a crystalline solid lowered from 130 K to 0 K
(3). \(2\text{NaHCO}_3\left(g\right)\,\rightarrow\,\text{Na}_2\text{CO}_3\left(s\right)\,+\,\text{CO}_2\left(g\right)\,+\,\text{H}_2\text{O}\left(g\right)\)
(4). \( \text{Cl}_2(g) \rightarrow 2\text{Cl}(g) \)
