Answer:
The correct option is;
D. Petrol > Alcohol > Kerosene oil > Water
Explanation:
The volatility of a liquid is a measure of how readily it evaporates or vaporizes such that a volatile liquid will evaporate and be present as a vapor at a given temperature or pressure than a less volatile liquid
The volatility of a liquid is directly related to the liquid's vapor pressure such that the higher the vapor the more volatile the liquid
The Reid vapor pressures of the given liquids are as follows;
Alcohol (Ethanol)= 17-55 kPa
Petrol = 53-60 kPa
Kerosene Oil= 6.8 kPa
The vapor pressure for water at 37.8°C = 6.6 kPa
Therefore, the correct order evaporation is as follows, starting from the highest vapor pressure to the lowest;
Petrol > Alcohol > Kerosene Oil > Water.
