  1. Combustion.
  2. Dissolution of salts in water.
  3. Melting of ice.
  4. Condensation of steam.

Questions & Step-by-Step Solutions

Which of the following processes is associated with a positive enthalpy change?
  • Step 1: Understand what enthalpy change means. Enthalpy change (ΔH) indicates whether a process absorbs or releases heat.
  • Step 2: Identify the types of processes. An endothermic process absorbs heat, while an exothermic process releases heat.
  • Step 3: Recognize that a positive enthalpy change (ΔH > 0) means heat is absorbed.
  • Step 4: Consider the melting of ice. When ice melts, it absorbs heat from the surroundings.
  • Step 5: Conclude that since melting ice absorbs heat, it is an endothermic process and has a positive enthalpy change.
