SUMMARY
The required pressure difference to heat 2 moles of gas from 12 K to 276 K in a volume of 0.001 m³ can be calculated using the ideal gas law, PV=nRT. The calculations involve substituting the values for pressure (P), volume (V), number of moles (n), the gas constant (R), and temperature (T) into the equation. The correct approach is to calculate the pressure at both temperatures and then find the difference, ensuring that Avogadro's number is not used incorrectly in the calculations.
