Benzene (C6H6) is a common organic solvent. The vapor pressure of benzene at 25°C is 104 mmHg. The normal boiling point of benzene is 80.1°C. a) If the temperature is decreased from 25°C to 0°C, the vapor pressure of benzene will be [boolean7] 104 mmHg. b) At 700 mmHg, benzene will boil at a temperature [boolean8] 80.1°C.
