The energy needed to raise the temperature of water from 22.0ºC to 90.0ºC is c. 28.4 kJ.
<h3>What is specific heat?</h3>
The amount of energy needed to raise the temperature of one gram of a substance by one degree Celsius.
By the formula 
Q is the heat
m is the mass
c is the specific heat
Now, c = 4.184 J/g.K
The change in temperature is 22.0 ºC to 90.0 ºC
Putting the value in the equation
Thus, the energy needed to raise the temperature of water from 22.0ºC to 90.0ºC is 28.4 kJ

The strongest intermolecular bonding in ethanol is hydrogen bonding.
Intermolecular forces are the forces that hold two molecules of a substance together in a given state of matter. For ethanol, the strongest intermolecular force is hydrogen bonding.
Hydrogen bonding occurs when hydrogen is directly linked to a highly electronegative element such as oxygen, nitrogen, fluorine or sulfur. The existence of intermolecular hydrogen bonds accounts for unusual properties such as abnormally high melting and boiling points.
