Answer:
33400 J
Question:
The specific heat of water is 4.18 J/g•°C. How much heat does 225.0 g of water release when it cools from 85.5°C to 50.0°C? Enter your answer below, in whole numbers, without any commas.
The heat that is released when 225.0 g of water is cooling down is 33400 J.
What is specific heat?
The amount of energy needed to raise the temperature of one gram of a substance by one degree Celsius.
By the formula of specific heat
[tex]q = mc \Delta T[/tex]
where q = transfer of heat
m = mass of the water; 225.0
c = specific heat; 4.18 J/g
T = change in temperature 85.5 and 50.0
Now, putting the values in the equation
[tex]\rm q = 225.0 \times 4.18\; J/g ^\circ C \times (85.5 ^\circ C - 50.0 ^\circ C ) = 33,387 J[/tex]
Thus, the heat released by water is 33400 J.
