What is the main difference between evaporation and boiling?

The correct answer is Evaporation occurs at any temperature, while boiling occurs at a specific temperature..

Practical lens: Link apparatus, readings, and uncertainty to the exact measurement named in the objective. This question asks: What is the main difference between evaporation and boiling. The correct response is Evaporation occurs at any temperature, while boiling occurs at a specific temperature., because changes of state are explained by particle energy and arrangement. In Changes of state, the marking point should connect directly to explain evaporation as particles escaping from the surface of a liquid. If the question includes values, the working must keep the appropriate unit and operation; if it is an explanation, it must name the relevant particle behaviour or energy change. This item belongs to Changes of state and the particle model, so avoid answers that switch to a different quantity, confuse heat with temperature, or describe gas pressure without collisions when collisions are the reason. Checkpoint 146 is distinct because it uses this exact question context and the practical lens rather than a generic particle-model sentence.
