A system releases 661 kJ of heat and does 100 kJ of work on the surroundings. What is the change in internal energy of the system?
1. A system releases 654 kJ of heat and does 140 kJ of work on the surroundings. What is the change in internal energy of the system? 2. How much heat is required to warm 1.30 L of water from 26.0 ∘C to 100.0 ∘C? (Assume a density of 1.0g/mL for the water.) Express your answer using two significant figures..
A system does 531 kJ of work and loses 241 kJ of heat to the surroundings. What is the change in internal energy, Δ E , of the system? Note that internal energy is symbolized as Δ U in some sources.
A combustion reaction releases 345 KJ of heat and produces gas that does 29 Kcal of work on the lid of the container. What is the change of energy? 29kcal = 121.336 KJ Since the reaction releases 345 KJ and then does 121.336 KJ of work on the lid of a container, I thought both would be negative, but the correct answer in our practice quiz says they should both be positive. I got -466 KJ and it says it...
