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

<u>Given the following data:</u>

  • 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

<em>Change in internal energy, </em>\Delta E<em> = </em><em>1644 Joules.</em>

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

A very hot cube of copper metal (32.5 g) is submerged into 105.3 g of water at 15.4 0C and it reach a thermal equilibrium of 17.
zysi [14]

Answer:

The initial temperature of the metal is 84.149 °C.

Explanation:

The heat lost by the metal will be equivalent to the heat gain by the water.  

- (msΔT)metal = (msΔT)water

-32.5 grams × 0.365 J/g°C × ΔT = 105.3 grams × 4.18 J/g °C × (17.3 -15.4)°C

-ΔT = 836.29/12.51 °C

-ΔT = 66.89 °C

-(T final - T initial) = 66.89 °C

T initial = 66.89 °C + T final

T initial = 66.89 °C + 17.3 °C

T initial = 84.149 °C.
