Question

Calculate ΔE, if q= 0.764 kJ and w= -880 J .

Answer 1

The change in internal energy of the system is 1644 Joules.

Given the following data:

• Heat added, Q = 0.764 kJ

• Work done = -880 Joules

To find the change in internal energy of the system, we would apply the First Law of Thermodynamics.

Mathematically, the First Law of Thermodynamics is given by the formula:

$\Delta E = Q - W$

Substituting the values, we have:

$\Delta E = 0.764(10^3) - (-880)\\\\\Delta E = 764 + 880$

Change in internal energy, $\Delta E$ = 1644 Joules.

Therefore, the change in internal energy of the system is 1644 Joules.
