heres the whole expeiriment if you need more info :))

Respuesta :

Answer and explanation;

  • The experimental data might differ from the theoretical value because because the Theoretical value is calculated under ideal conditions such as there  is no heat loss to the environment or surroundings, constant temperature and pressure, the use of ideal gasses and fluids etc.
  • While on the other hand, experimental data is obtained under real environment conditions such as changing temperature and pressure, accompanied by loss of heat to the surroundings, the gases are not ideal
