Benzene is a starting material in the synthesis of nylon fibers and polystyrene (styrofoam). its specific heat capacity is 1.74 j/g·k. if 16.7 kj of energy is absorbed by a 225-g sample of benzene at 20.0°c, what is its final temperature? *hint check what number the question is asking for>
a. –22.7°c
b. 36.7°c
c. 42.7°c
d. 62.7°c
e. none of these choices is correct

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 absorbed= 16.7 kJ = 16700 J  (1kJ=1000J)

m= mass of benzene = 225 g

c = specific heat capacity = 1.74 J/gK

Initial temperature of the water = = 20.0°C  = 293 k  

Final temperature of the water =  = ?

Change in temperature ,

Putting in the values, we get:

The  final temperature will be

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
