What is the main difference between evaporation and boiling?
What is the main difference between evaporation and boiling?
- Evaporation occurs only at the surface of a liquid, while boiling occurs throughout the liquid (correct)
- Evaporation involves molecules gaining energy, while boiling does not require energy input
- Evaporation results in a change of state, while boiling does not change the state of the substance
- Evaporation happens at all temperatures, while boiling only occurs at one specific temperature
What happens to the temperature of a liquid during boiling?
What happens to the temperature of a liquid during boiling?
- The temperature of the liquid decreases continuously
- The temperature of the liquid fluctuates randomly
- The temperature of the liquid remains constant until all molecules turn into a gas (correct)
- The temperature of the liquid increases continuously
