Assignment

1. Diagrammatically explain the features of calorimetry.
2. Calculate the heat capacity of the calorimeter.
   Given: 50 mL warmer water at 37.9 °C, 50 mL cooler water at 20.9 °C, final mixed temperature 29.1 °C. Specific heat of water = 4.184 J·g⁻¹·°C⁻¹, density of water = 1 g·mL⁻¹.
3. Calculate the heat capacity (in kJ·K⁻¹) of a calorimeter when its temperature increases by 0.3 K after absorbing 30.0 J of energy.
4. Discuss the difference between constant-volume and constant-pressure calorimetry.
5. How will you determine the water-equivalent of a calorimeter? Discuss.
