Why are pennies good for simulating radioactive atoms? Check all that apply. Pennies have two sides—one to represent radioactive

form and another to represent nonradioactive form. You can easily see the two different forms. You can create a large sample of pennies. Pennies are not actually hazardous. The chance of an atom decaying during a half-life cycle is 50%, the same as flipping a coin and getting tails.

Vladimir [108]

Los cambios de estado físico son transformaciones que ocurren de un estado de la materia a otro, sin cambiar la estructura molecular de la materia, es decir, sin transformarse en otras sustancias.

Los tres estados físicos básicos de la materia son:

  1. sólido,
  2. líquido y
  3. gaseoso.

Se puede decir que son diferentes solo por la organización de sus partículas, lo que determina su cambio de estado pero sin cambiar la estructura molecular.

Cualquier sustancia se puede encontrar en estos tres estados físicos, dependiendo de su temperatura y presión.

El aumento de temperatura hace que las moléculas se separen y el aumento de presión hace que se acerquen.

En estado sólido las partículas están más juntas, en el líquido se mueven más y en el gas están bien separadas.

Is there a qualitative difference between the enthalpy of a phase transition versus the enthalpy of a heating or cooling process
Vesna [10]

Answer:

No

Explanation:

given that, enthalpy is a state function, that means it depends only on the initial and final states,  there is no difference between the enthalpy of a phase transition versus the enthalpy of a heating or cooling process, when the cooling or heating process finish in a change of phase.

It does not  matter which way we take to cool or heat the substances the Enthalpy of this process will be the same.
