Question

Ordinary water boils at 100°C. Can it be made to boil at 95°C or 105°C? Explain.

Answer 1

On Increasing and decreasing pressure ,water can boils at 105°C and 95°C respectively.
at high altitudes atmospheric pressure is low so there water boils below 100°C.
Addition of volatile solution also differs the boiling point of water.

Answer 2

sure.
two possible ways:
if thermometer is giving incorrect readings of ±5 °C. joking.

here's the answer:
if water has more latent heat already (as required), then it will start boiling at temperatures lower than 100 °C.
and vice versa.

And also by changing the pressure

Tell me if that's correct or not, What do you think?
