WebNext the time and temperature were recorded every minute for 18 minutes. All the data was recorded in a data table. Next the beaker was put on a hot plate and the temperature was taken and recorded every 30 seconds. Then the water was left to continue boiling for 5 more minutes and time and temperature were recorded every 30 seconds. WebAlso described was the use of heating and cooling curves to determine a substance’s melting (or freezing) point. Making such measurements over a wide range of pressures … WebThe vapour pressure of water is the pressure exerted by molecules of water vapor in gaseous form (whether pure or in a mixture with other gases such as air). The saturation vapour pressure is the pressure at which water vapour is in thermodynamic equilibrium with its condensed state.At pressures higher than vapour pressure, water would condense, … emporia parole office
