Which of the following processes involves a change of state without a change in temperature? (2018)
Step 1: Understand what a change of state means. This refers to the transformation of a substance from one physical form to another, such as solid to liquid or liquid to gas.
Step 2: Identify the processes that involve a change of state. Common examples include melting (solid to liquid), freezing (liquid to solid), condensation (gas to liquid), and evaporation (liquid to gas).
Step 3: Learn about temperature during these processes. Some changes of state occur at a constant temperature, meaning the temperature does not increase or decrease during the change.
Step 4: Focus on melting. When ice melts to become water, it changes from solid to liquid, but the temperature remains constant at 0 degrees Celsius until all the ice has melted.
Step 5: Conclude that melting is the process that involves a change of state (from solid to liquid) without a change in temperature.
