Questions & Step-by-Step Solutions

In a calorimetry experiment, what does a positive q value indicate?
  • Step 1: Understand what 'q' means in calorimetry. 'q' represents the heat energy involved in a process.
  • Step 2: Know that 'q' can be positive or negative. A positive 'q' means heat is being absorbed.
  • Step 3: Recognize that when a system absorbs heat, it takes in energy from its surroundings.
  • Step 4: Conclude that a positive q value indicates the system is gaining heat.
  • Heat Transfer – A positive q value signifies that heat is being absorbed by the system, indicating an endothermic process.
