Water is to be boiled at sea level in a 30-cm-diameter stainless steel pan placed on top of a 3-kW electric burner. If 60% of the heat generated by the burner is transferred to the water during boiling, determine the rate of evaporation of water. See Figure 2-39 attached.
Please show steps.Thanks.
Determining Gas Pressure, Vapor Pressure, and Evaporation Rate
1. 75-100 words, explain in molecular terms, why the pressure of gas increases when the temperature increases.
2. 75-100 words, explain in molecular terms, whether the vapor pressure of gas varies with temperature.
3. 75-100 words, explain in molecular terms, whether evaporation rate of a liquid is constant or varied in the presence of changing ambient air pressure.View Full Posting Details
