A heated copper block at `130^(@)C` loses 340 J of heat to the surroundings, which are at room temperature of `32^(@)C`. Calculate total entropy change in the universe due to this process.

Text Solution

AI Generated Solution

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