A reaction absorbs 400 J of heat, and during this process, it does 100 J of work on the surroundings. Calculate the change in internal energy of the system.
💡 Hint: Apply the formula ∆U = q + w correctly.
In a calorimetry experiment, a student measures a temperature increase of 2 °C in the water surrounding a bomb calorimeter containing 1.0 g of a substance that released 2000 J of heat. Calculate the heat capacity of the calorimeter.
💡 Hint: Use the relationship of heat release and temperature change.
