1 When the temperature of a liquid is raised enough, the liquid boils. This means that bubbles of vapor, containing millions of molecules, form below the surface. In order for such bubbles to be produced, the pressure of the vapor inside them must be equal to the pressure of the air upo...
What condition must exist for a liquid to boil? Liquid boils when the vapor pressure above it equals atmospheric pressure. TL;DR (Too Long; Didn't Read) The key is to know which bonds require more energy for boiling to occur. **Bond strength** rated strongest to weakest: ...
View Solution A liquid is in equilibrium with its vapour at a certain temperature. If ΔHvap=60.24kJmol−1andΔSvap=150.6Jmol−1 then the boiling point of the liquid will be View Solution A liquid boils when its vapour pressure equals View Solution ...
When water is a liquid(液体), we drink it or use it to take a shower. When water is a solid(固体), we put some of it into a drink to keep it cool. We like to ski or skate on solid water. When water is a gas, we call it water vapour. When water boils(煮沸), some of ...
英语翻译 The temperature at which a liquid boils is dependent on the pressure being exerted on it.The vapor pressure of the liquid is the pressure being exerted by the tiny molecules seeking to escape the liquid and become vapor.Vapor pressure increases with an increase in temperature until at...
In addition, when investigating processes occurring when liquid helium boils in a centrifugal force field, its thermodynamic parameters may be close to the critical values, and the dependences of the thermophysical properties of the liquid and vapor on the temperature and pressure must be taken into...
