To calculate the total entropy change in the universe due to the process where a heated copper block loses heat to the surroundings, we can follow these steps: ### Step 1: Convert temperatures to Kelvin - The temperature of the copper block (system) is given as \(130^\circ C\). To convert this to Kelvin: \[ T_{system} = 130 + 273 = 403 \, K \] - The temperature of the surroundings is given as \(32^\circ C\). To convert this to Kelvin: ...
