Answer: Thus 663 J of heat is released when 27.6 g 
cools from 83.1 °C to 55.6 °C
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 released = ?
m = mass of substance = 27.6 g
C = specific heat capacity = 
Initial temperature= 
= 
Final temperature = 
= 
Change in temperature ,
Putting in the values, we get:
As the value of q is negative, it means the heat has been released and it is 663J
"Normal red blood cells are rounded and disk-shaped. In sickle cell anemia, some red blood cells become deformed, so they look like sickles used to cut wheat. These unusually shaped cells give the disease its name. Sickle cell anemia is one of a group of disorders known as sickle cell disease."

At the boiling point, external pressure is equal to the vapor pressure of water. Therefore, the vapor pressure of water at an ecternal pressure of 404 kPa is equal to 404 kPa as well. Hope this answers the question. Have a nice day. Feel free to ask more questions.
