Describe an experiment to determine the saturation vapour pressure of water in the temperature range 25 degrees Celsius to 70 degrees Celsius . Sketch the curve you would expect to obtain
The experiment to determine the saturation vapour pressure of water in the temperature range 25 degrees Celsius to 70 degrees Celsius would involve the use of a closed container with a known volume. The container would be filled with water and heated to the desired temperature. The pressure of the water vapour in the container would then be measured using a pressure gauge. This process would be repeated for each temperature in the range.
The expected curve would be a graph of the saturation vapour pressure of water against temperature. The graph would show an increase in the saturation vapour pressure as the temperature increases. The curve would be approximately linear in the range 25 degrees Celsius to 70 degrees Celsius.
