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

Answer: is neither an acid nor a base
Explanation: Water is a universal solvent which means it can dissolve most of the substances in it.
Water has high thermal heat capacity , which means large heat is required to heat the water.
Water is not always pure as it gets contaminated by various pollutants present in the atmosphere such as gases, bacteria and suspended matter.
Water is an amphoteric substance which can act as both acid and base, thus can donate and acept [texH^+[/tex] ions.Thus it is neither an acid nor a base.
Here water is accepting a proton, thus it acts as base.
Here water is donating a proton, thus it acts as acid.

Answer: 
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed by calorimeter =
Joules
C = heat capacity of calorimeter = ?
Initial temperature of the calorimeter = 
= 22.37°C
Final temperature of the calorimeter = 
= 24.68°C
Change in temperature ,
Putting in the values, we get:
The heat capacity of the calorimeter is
