Asystem has 32 kj of work performed on it and absorbs 52,000 j of heat. what is the change in the internal energy of the system

84 kJ is the change in the internal energy of the system.

Explanation:

According to thermodynamic,Change in energy is sum of heat added to system and work done on the system.:

ΔE = Q + W

Where:

ΔE = change in internal energy

Q = energy added to the system

W =  Work done on the system

According to question, we have :

W = 32 kJ = 32,000 J ( kJ=1000 J)

Q = 52,000 J

84 kJ is the change in the internal energy of the system.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
