Dalton’s completing an investigation in the science lab. he observes that a sample of liquid turns to gas at 135°c. what’s this temperature called?
a boiling point
b freezing point melting point
c room temperature
d standard temperature

Answer : Option A) Boiling Point.

Explanation : The sample of liquid when turns into gas at 135°C is called as boiling point of that liquid.

Boiling point is the temperature at which a liquid boils and turns into vapour state.

So, when Dalton was investigating in the lab. He observed that liquid turns into vapour it can be called as boiling point of that liquid.
