Bomb Calorimetry Simulation

Measuring the energy content of food using calorimetry

Measure the energy (calorie) content of different food items by burning them and measuring the heat transferred to water.

Measuring enthalpy of neutralization using a simple calorimeter

Determine the enthalpy of neutralization of HCl and NaOH using a polystyrene cup calorimeter.

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 …

Barium hydroxide and ammonium thiocyanate cold reaction

Demonstrate a dramatically endothermic reaction where the mixture becomes cold enough to freeze water on the outside of the flask.

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 …

Measuring the heat released during instant crystallization

Quantify the heat released during the crystallization of supersaturated sodium acetate using calorimetry.

Determining ΔH using Hess's law and magnesium oxide

Determine the enthalpy of combustion of magnesium indirectly using Hess's law, since direct measurement is impractical.

Confirming that enthalpy is a state function using three reactions

Verify Hess's law by measuring the enthalpy changes of three related reactions and showing that ΔH1 + ΔH2 = ΔH3.

Comparing heat capacities of aluminum, copper, and iron

Determine the specific heat capacity of several metals using the method of mixtures and compare with accepted values.
