The boiling point of ethanol is 78.3^circ C The boiling point of ethanol on the Kelvin scale is approximately - 26K 351 K 451 K 178 K

To convert the boiling point of ethanol from Celsius to Kelvin, you can use the formula:<br /><br />\[ K = ^{\circ}C + 273.15 \]<br /><br />Given that the boiling point of ethanol is \(78.3^{\circ}C\), the conversion to Kelvin would be:<br /><br />\[ K = 78.3 + 273.15 = 351.45 \, K \]<br /><br />Therefore, the boiling point of ethanol on the Kelvin scale is approximately \(351 \, K\).<br /><br />The correct answer is: **351 K**.
