Let's see . . .

196 kj came out of the system

428.4 kj went into the system

The difference is 232.4 kj, and more energy went in than came out.

So the whole process increased the internal energy of the system by 232.4 kj.

The change is equal to final-initial.

428-255 = 173 cal

The system adsorbs energy from its surroundings?

An Endothermic change is the system that absorbs energy from its surroundings.


What is the change in internal energy if 20 joules of heat is released from a system and the system does 50 joules of work on the surroundings?

A system absorbs 640J heat and does work of 260J the change in internal energy of the system will be?

the system has been given internal energy of 640j and the work system does on surroundings is 260j. therefore by first law of thermodynamics the internal energy of system increases by (640-260=380)j.


A system gives off 196KJ of heat to the surroundings and the surroundings do 420 KJ of work on the system What is the change in internal energy of the system?

When reactants change to products do the chemicals lose or gain energy?

The formation of bonds causes an energy release, while the breaking of bonds causes an absorption of energy. In a combustion reaction c+o2 --> co2, the reactants have a higher internal energy than the products resulting in a negative internal energy because energy is flowing out of the system to the surroundings. However in co2 ---> c+o2, the reactants have a lower internal energy than the products, so the internal energy of the system is positive as energy is flowing into the system from the surroundings.


What is a exothermic change?

It is when something releases its energy to its surroundings do to a system.


If work is don adiabatically on a system will the internal energy increase or decrease?

If work is done adiabatically on a system, the internal energy will increase. This is because adiabatic processes do not involve the exchange of heat with the surroundings, so any work done on the system will directly contribute to an increase in its internal energy.


Which one of the following conditions would always result in an increase in the internal energy of a system?

the system gains heat and does work on the surroundings


A system delivers 225 J of heat to the surroundings while delivering 645 J of work Calculate the change in the internal energy ΔE of the system?

∆E (internal energy) = q (heat flow) + w (work) The question says that heat is delivered to the surroundings (therefore lost by the system so (-)). Also, It says in the same statement work is being delivered, so work is also negative. ∆E = -225J + (-645J) = -870


Does a closed system exchange energy with the outside?

Yes it can... An open system can exchange both energy and matter with its surroundings, where as a closed system CAN exchange energy, but CANNOT exchange matter with its surroundings. Also, an isolated system cannot exchange energy nor matter with its surroundings.


When a solid changes to liquid will it gain or lose energy?

It looses energy to the surroundings. When bindings brakes, energy is released.
