What is enthalpy of water at room temperature? - Answers
WebNov 21, 2024 · When liquid water reaches a low enough temperature, it freezes and becomes a solid—ice. When solid water is exposed to enough heat, it will melt and return to a liquid. As that liquid water is further heated, it evaporates and becomes a gas—water vapor. Is 30 degrees Celsius room temperature? Room temperature: 1°C – 30°C. WebJan 18, 2024 · Define your first point. For example, water boils at 100 °C when pressure is 1atm. Obtain the water enthalpy of vaporization: 40660 J/mol. Also, remember we are going to use the gas constant: 8.3145 J/mol×K; Resolve the vapor pressure equation considering the 2nd point pressure is 0.6 atm. You will get the resulting temperature: … the bud of a joke
