the shape of the water the rate of evaporation the boiling point of water the amount of steam released per minute
I gave my students this multiple choice question: An experiment was performed at sea-level. 400 mL of water was put in 4 different-shaped containers and placed on hot plates with 4 different temperature settings as shown below. Beaker - 110°C Petri dish - 95°C Erlenmeyer flask - 60°C Round bottom bowl - 45°C Which characteristic of water remained the same in each container?

Only one answer is correct among these 4 choices:
- the shape of the water
- the rate of evaporation
- the boiling point of water
- the amount of steam released per minute

Could you tell me which one is correct?

the boiling point of water
