Question

Normal temperature and pressure one water sample boils at 373k temperature.Is water pure?Is these water made ice at 273k temperature?explain

Answer 1

For water, the vapour pressure reaches the standard atmospheric pressure of 1 atmosphere at 100°C. So the normal boiling point of water is 100°C (212°F or 373K).The boiling point of pure water increases on the addition of soluble substances such as sugar or common salt.

Answer 2

yes the sample of water is pure. the boling and melting point of water is 373.2 and 273.2 respectively and the boiling and melting point of water is nearly same. therefore the given sample of water is pure
