How much heat is required to raise the temperature of 179g of acetic acid, CH3COOH, from 250C to 82.70C?

Respuesta :

Answer: The heat required to raise the temperature of 179 g of acetic acid, is 21000 Joules

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

[tex]Q=m\times c\times \Delta T[/tex]

Q = Heat absorbed  = ?

m = mass of acetic acid = 179 g

c = heat capacity of acetic acid = [tex]2.043J/g^0C[/tex]

Initial temperature  = [tex]T_i[/tex] = [tex]25^0C[/tex]

Final temperature = [tex]T_f[/tex]  = [tex]82.7^0C[/tex]

Change in temperature ,[tex]\Delta T=T_f-T_i=(82.7-25)^0C=57.7^0C[/tex]

Putting in the values, we get:

[tex]Q=179g\times 2.043J/g^0C\times 57.7^0C=21100J[/tex]

Thus heat required to raise the temperature of 179 g of acetic acid, is 21000 Joules
