Coffee Cup Calorimetry Part A Calorimetry is a method used to measure enthalpy, or heat, changes that occur during chemical processes. Two common calorimeters are constant-pressure calorimeters and constant- valume (or 'bomb) calorimeters. Bomb calorimeters are used to measure combustion and other gas-producing reactions, where the reaction is observed in a strong, sealed vessel. A simple constant-pressure calorimeter can be made from a foam coffee cup and a thermometer; energy changes in a reaction are observed via a temperature change...

Bomb calorimetry is also known as constant-volume calorimetry because the volume of the reaction container does not change. Which of the following can be said of the change in internal energy of the system relative to the heat produced/released by the reaction being measured in a bomb-calorimeter? Hint: What can be said of work if the volume is constant? Group of answer choices ΔE > q ΔE = q ΔE < q

In one of the General Chemistry experiments, you used a coffee-cup calorimeter to measure the heat of neutralization of selected acid-base reactions. The calorimeter consisted of two nested Styrofoam cups with a cardboard lid. A temperature probe was lowered in the solution through a hole in the lid. Is a coffee-cup calorimeter a constant-volume or a constant-pressure device? Is a coffee-cup calorimeter adiabatic? The coffee-cup calorimeter was calibrated by using the neutralization reaction between sodium hydroxide and hydrochloric acid. The...

Coffee Cup Calorimetry: Solution Enthalpy
When a solid dissolves in water, the solution may become hotter or colder. The dissolution enthalpy (dissolving) can be determined using a coffee cup calorimeter. Thermometer In the laboratory a general chemistry student finds that when 1.46 g CaCl(s) is dissolved in 113.70 g water, the temperature of the solution increases from 22.49 to 24.83 °C.
