To solve the problem, we will follow these steps: ### Step 1: Understand the Given Information We have a helium gas in a vessel that expands at constant pressure when 15 kJ of heat is supplied. We need to find the change in internal energy (ΔU) and the work done (ΔW) during this expansion. ### Step 2: Apply the First Law of Thermodynamics The First Law of Thermodynamics states: \[ ...
