Question
![### Experimental Description
A mixture of gaseous reactants is contained in a cylinder where a chemical reaction converts them into gaseous products. The system is equipped with a piston that adjusts its position to maintain a constant pressure of 1 atm. The entire setup is submerged in a large insulated water bath for controlled conditions. The chemical reaction in the cylinder is exothermic, releasing 101 kJ of energy, as determined from prior experiments. During the reaction, the system performs 340 kJ of work on the piston.
### Diagram Explanation
The diagram illustrates a cylindrical setup with a piston at the top. The piston moves to maintain the pressure at 1 atm. Surrounding the cylinder is a water bath, which is insulated to prevent heat exchange with the environment. A thermometer indicates the water bath's temperature.
### Questions and Options
1. **Is the reaction exothermic or endothermic?**
- [x] exothermic
- [ ] endothermic
2. **Does the temperature of the water bath go up or down?**
- [ ] up
- [x] down
- [ ] neither
3. **Does the piston move in or out?**
- [ ] in
- [x] out
- [ ] neither
4. **Does heat flow into or out of the gas mixture?**
- [ ] in
- [x] out
- [ ] neither
5. **How much heat flows? Round your answer to 3 significant digits.**
