Concept explainers
A mixture of gases A2 and B2 are introduced to a slender metal cylinder that has one end closed and the other fitted with a piston that makes a gas-tight seal so that the gases are a closed system. The cylinder is submerged in a large beaker of water whose temperature is 25 °C, and a spark is used to trigger a reaction in the cylinder. At the completion of the reaction, the piston hasmoved downward, and the temperature of the water bath has increased to 28 °C. If we define the system as the gases inside the cylinder, which of the following best describes the signs of q, w, and SE for this reaction?
- q< 0, w< 0, ΔE< 0
- q< 0, w> 0, ΔE< 0
- q< 0, w> 0, the sign of ΔE cannot be determined from the information given
- q>0, w>0, ΔE>0
- q>0, w< 0, the sign ofΔE cannot be determined from the information given
