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.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
