Question

The diagram shows some apparatus that can be used to investigate what happens when
candle bums. The soda lime absorbs the carbon dioxide produced as the candle bums.
to pump
at the start of the experiment a fine Mist of tiny water droplets appears on the inside of the funnel where has this water come from explain why the water disappears soon after the experiment starts ​

Answer 1

Answer:

In the previous module, the variation of a liquid’s equilibrium vapor pressure with temperature was described. Considering the definition of boiling point, plots of vapor pressure versus temperature represent how the boiling point of the liquid varies with pressure. Also 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 yields data that may be presented graphically as a phase diagram. A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). A typical phase diagram for a pure substance is shown in Figure 1.

Answer 2

Explanation:

• The water comes from evaporation.
