Nettet20. apr. 2024 · The mass is still 18.0 grams but the specific heat now, since we have liquid water, we need to use the specific heat of liquid water, which is 4.18 joules per gram degrees Celsius. And … NettetThe length of the line of the heating curve for water at 100 °C is the amount of heat required to change all of the liquid into a gas. This heat is called the change in enthalpy of vaporization, Δ H vap. Vaporization is a specific scientific term for changing a pure liquid into the gas phase.

At 3 P.M. (15:00 on the graph), Louisville reported a temperature of 81 degrees Fahrenheit, but an hour later, the temperature was only 73 degrees Fahrenheit. NettetEvaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. High concentration of the evaporating substance in the surrounding gas significantly slows down evaporation, such as when humidity affects rate of evaporation of water. When the molecules of the liquid collide, they transfer energy to … sycamore 2158
