Solve the following question given below:
Question: 6.42 moles of an ideal gas expands isothermally from 3.36 m3 to 8.72 m3 at a temperature of 421 Celsius.
Part A- How much heat (in Joules) was added?
I need help to solve the above question and express your result in scientific notation and to three significant digits. Hint: what is the change in the internal energy of an ideal gas during an isothermal process? Be careful with signs!
