The boiling point of liquid nitrogen is -195.81 degree C at atmospheric pressure. Express this temperature in (a) F degree (b) K. How many Joules of thermal energy must be added to 5 \ kg of water at 20^{\circ} C to bring it to the boiling point at 100^{\circ} C?
JohnCarroll, inNatural Gas Hydrates (Third Edition), 2014 1.2.1The Normal Boiling Point of Water As an example of the unusual properties of water, consider theboiling point. We will use some simple chemistry to demonstrate that the boiling point of water is unusually high. The boiling points...
Boiling Point:It is defined as the boiling point of a liquid, at the temperature at which its vapor pressure is equal to the pressure of the gas over the liquid. As the temperature is increased, the vapor pressure increasesAnswer and Explanation: ...
