Question

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 C. melting point D. room temperature E. standard temperature

Answer 1

Answer:

option a

Explanation:

Answer 2

The temperature at which the sample of liquid turns to gas at 135 °C is termed as boiling point.

Answer: Option A

Explanation:

The observation of conversion of liquid to gas indicates that there is occurrence of change in the state of matter. The inter-conversion from one state to another can be done by either varying the temperature or by varying the pressure.

In this case, the liquid on heating gets converted to gaseous state after attaining a particular temperature say 135 °C. So, this process of conversion from liquid to gaseous state on heating is termed as boiling.

The temperature at which a liquid converts to gas is termed as the boiling point of that liquid.
