If the thermal energy of the system increases by 400 J, and 1,100 J of heat were added to the system, how much work did the syst
Luba_88 [7]

700 J is the work done by the system.

<u>Explanation:</u>

The first law of thermodynamics is that the change in internal energy of the system is equal to the net heat transfer to the system minus the complete work performed by the system.

                  \Delta \boldsymbol{U}=\boldsymbol{Q}-\boldsymbol{W}

Where,

∆U – Change in internal energy

Q – Heat transfer to the system

Q – Work done

Here,

<u>Given data:</u>

∆U - 400 J

Q - 1100 J

We need to the work done by the system (W)

By applying the given values in the above equation, we get

400 = 1100 - W

W = 1100 - 400 = 700 J

I would like to know how can I practice physics grade 10 questions?​
Vanyuwa [196]

Answer:

Go to K.han Academy and look up High School Physics on there. Other than that You.Tube has some physics curriculums which probably have practice questions. If not you could just pause the video and see if you can answer the questions they're going over yourself. Also, searching up "Physics Worksheet" and such may help.
