Heat Transfer between Substances at Different Temperatures. A 360-g piece of rebar (a steel rod used for reinforcing concrete) is dropped into 425 mL of water at 24.0 °C.
Identifying a Metal by Measuring Specific Heat. A 59.7 g piece of metal that had been submerged in boiling water was quickly transferred into 60.0 mL of water initially at 22.0 °C.
Heat Produced by an Exothermic Reaction. When 50.0 mL of 0.10 M [latex]\ce{HCl}[/latex](aq) and 50.0 mL of 0.10 M [latex]\ce{NaOH}[/latex](aq), both at 22.0 °C, are added to a coffee cup calorimeter, the temperature of the mixture reaches a maximum of 28.9 °C.
Heat Flow in an Instant Ice Pack. When solid ammonium nitrate dissolves in water, the solution becomes cold. This is the basis for an “instant ice pack” (Figure 10.2.6).
Bomb Calorimetry. When 3.12 g of glucose, [latex]\ce{C6H_{12}O6}[/latex], is burned in a bomb calorimeter, the temperature of the calorimeter increases from 23.8 °C to 35.6 °C.
