SUMMARY
The problem involves calculating the new temperature of an ideal gas after a 35% reduction in thermal energy from an initial temperature of 40°C. The correct approach requires converting the Celsius temperature to Kelvin, as thermal energy is proportional to absolute temperature. The initial temperature in Kelvin is 313.15 K, and after reducing the thermal energy by 35%, the new temperature is calculated to be 243.15 K, which converts to -30°C. The initial calculation of 26°C was incorrect due to not accounting for the absolute temperature scale.
