Answer:

109.97JK-1

Explanation:

Entropy is the degree of disorderliness of a substance. It is given by ∆H/T where T is the absolute temperature in Kelvin.

Given ∆H= 38.6*10^3

T=78°C+ 273=351K

∆S=38.6*10^3/351=109.97JK-1 as shown the diagram.

Describe the kinds of potential energy that are stored by a car driving on a hill.
Ilia_Sergeevich [38]

Answer:

The internal combustion engine in the car converts the potential chemical energy in gasoline and oxygen into thermal energy which is transformed into the mechanical energy that accelerates the vehicle (increasing its kinetic energy) by causing the pressure and performing the work on the pistons.
