A system transfers 20 kJ of heat to the surroundings. Write the value of q for both the system and surroundings.

Text Solution

AI Generated Solution

To solve the problem, we need to analyze the heat transfer between the system and the surroundings. Here's the step-by-step solution: ### Step 1: Understand the Heat Transfer The problem states that a system transfers 20 kJ of heat to the surroundings. This indicates that the system is losing heat. ### Step 2: Determine the Value of q for the System Since the system is losing heat, we represent this heat transfer with a negative sign. Therefore, the value of q for the system is: \[ ...
