Cold Pack Chemistry

Studying the endothermic dissolution of ammonium nitrate

Measure the temperature change when ammonium nitrate dissolves in water, demonstrating an endothermic dissolution process used in instant cold packs.

Comparing temperature changes of different salt dissolutions

Compare the enthalpy of dissolution of different salts (NaOH, CaCl₂, NH₄NO₃, KNO₃) to show that dissolution can be exothermic or …

Measuring the energy required to melt ice

Determine the enthalpy of fusion of ice by adding a known mass of ice to warm water and measuring the …
