Heat of vaporization = 204 cal/g
Melting point = -114.3 degrees Celsius
Boiling point = 78.5 degrees Celsius

condensation occurs at the boiling point of EtOH
∆H = mass x heat of vaporization.....to condense, energy is released
∆H = 25g x 204cal/g = 5100cal
now, since you don't give specific temperatures or even 1 temperature at which the EtOH is initially found, i only concentrated on condensation at the boiling point
