Un mol de un gas monoatómico cuyo calor absorbido es 40.0 J y cuyo trabajo recibido es 200.0 J experimenta un cambio de energía interna de 240.0 J.
Tenemos un mol de un gas monoatómico en un recipiente con un pistón y suceden las siguientes transferencias de energía:
- El gas absorbe 40.0 J de calor, ya que Q > 0.
- El gas recibe 200.0 J de trabajo, ya que Q > 0.
Podemos calcular el cambio de energía interna del gas (ΔU) usando la siguiente fórmula.
Un mol de un gas monoatómico cuyo calor absorbido es 40.0 J y cuyo trabajo recibido es 200.0 J experimenta un cambio de energía interna de 240.0 J.

<em>7. Considere un sistema que contiene un mol de un gas monoatómico retenidito por un pistón. ¿Cuál es el cambio de energía interna del gas, Q: 40.0 J y W: 200.0J?</em>
The answer is B. Asteroids
Oxygen is transported in the blood in two ways: A small amount of O 2 (1.5 percent) is carried in the plasma as a dissolved gas. Most oxygen (98.5 percent) carried in the blood is bound to the protein hemoglobin in red blood cells. A fully saturated oxyhemoglobin (HbO 2) has four O 2 molecules attached.

Answer:
2. have no negative particle
Explanation:
Helium atoms contains 2 neutrons and 2 protons (or 2 electrons). Thus, it has a mass number of 4 and atomic number of 2.
Alpha particles are heavy and positively charged, which make them to be deflected in a magnetic or electric charge. So, the helium atoms used as alpha particles for the gold foil experiment must have no negative particle.
