Hi everyone
I need your help in the following problem:
Some dry ice (solid carbon dioxide) at -78oC is placed in a steel jar, which is subsequently sealed. The jar is immersed in a large beaker of water at room temperature until the dry ice has completely vaporized.
If the measured energy change was 580 J, was this an enthalpy change or an internal energy change?
Answer: internal energy change
My question is, why the answer is internal energy instead of enthalpy change? could be you please explain it to me
