Answer :
Final answer:
The vapor pressure of water at 105 degrees Celsius would be higher than 101.3 kPa, as the vapor pressure of substances increases with temperature.
Explanation:
The vapor pressure of water at a given temperature refers to how much pressure is exerted by the water vapor in equilibrium with its liquid state at that temperature. In your question, you are asking about the vapor pressure of water at 105 degrees Celsius, which is a point beyond the boiling point of water at standard atmospheric pressure (100 degrees Celsius). We lack direct data for vapor pressure at 105 degrees Celsius, so none of the options A) 100 kPa B) 101.3 kPa C)110 kpa D.)120 kpa can be confirmed as correct without referencing a specific vapor pressure vs temperature graph or chart.
However, a basic principle to note is that as temperature increases, the vapor pressure of a substance also increases. This is because more molecules have the kinetic energy needed to escape from the liquid or solid phase into the gas phase. Therefore, we can expect the value to be higher than the standard atmospheric pressure of 101.3 kPa, given that 100 degrees Celsius corresponds roughly to this value.
By using the Clausius-Clapeyron equation, which relates the vapor pressure of a substance at one temperature to the vapor pressure of the same substance at another temperature, we could theoretically calculate the specific vapor pressure at 105 degrees Celsius, if we have data for a known temperature and vapor pressure. Typically, this information could be found in a table or graph in a physical chemistry textbook or reputable online resource.
