Benzene is a starting material in the synthesis of nylon fibers and polystyrene (styrofoam). its specific heat capacity is 1.74 j/g·°c. if 16.7 kj of energy is absorbed by a 225-g sample of benzene at 20.0°c, what is its final temperature?

The final temperature of the sample is 62.66°C

Explanation:

To calculate the amount of heat absorbed, we use the equation:

where,

Q = heat absorbed = 16.7 kJ = 16700 J   (Conversion factor:  1 kJ = 1000 J)

m = Mass of the sample = 225 g

c = specific heat capacity of sample =

= change in temperature =

Putting values in above equation, we get:

Hence, the final temperature of the sample is 62.66°C
