Answer:
-415 J
Explanation:
The amount of heat released when the ethylene glycol is cooled is given by:
where:
m = 3.65 kg = 3650 g is the mass of the ethylene glycol
Cs = 2.42 j/(g·°c) is the specific heat capacity of the substance
is the change in temperature of the coolant
By substituting the numbers into the equation, we find
And the sign is negative because the heat is released by the system.
The thermal process that occurs when pressure and volume are variable, while the temperature remains constant is known as an isothermal process. Due to the change in temperature being zero, the internal energy of the system does not change. Isothermal processes can be carried out adiabatically or non-adiabatically. (An adiabatic process is where the heat energy moving through the boundary of a system is 0)
I would think that you would have to do 42/2=21Hz, but I'm not sure...
