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

Answer 1

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

Step-by-step explanation:

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

`Q=m* c* \Delta T`

Q = Heat absorbed = ?

m = mass of acetic acid = 179 g

c = heat capacity of acetic acid =
`2.043J/g^0C`

Initial temperature =
`T_i` =
`25^0C`

Final temperature =
`T_f` =
`82.7^0C`

Change in temperature ,
`\Delta T=T_f-T_i=(82.7-25)^0C=57.7^0C`

Putting in the values, we get:

`Q=179g* 2.043J/g^0C* 57.7^0C=21100J`

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