ozzi

The ingredient's molecules would be more free and move faster, then the phase would change to liquid from solid.

<u>Explanation</u>:

  • This task seeks to examine the knowledge of the kinetic phase and characteristics of matters.
  • Here we see the chef described that the ingredient's molecules are moving in place – solid.
  • On the advent of causing the ingredient to change phase by transferring energy into it – the ingredient's molecules would be more free and move faster, then the phase would change to liquid from solid.

Identify the nuclide that would be formed from the alpha particle emission of Fm-257.
Elodia [21]

Answer: 1) The nuclide formed from the alpha decay of _{100}^{257}\textrm{Fm} is _{98}^{253}\textrm{Cf}

2) The nuclide formed from the beta-minus decay of _{98}^{253}\textrm{Cf} is _{99}^{253}\textrm{Es}

Explanation:

1) For alpha-decay

In this process, alpha particle is released.

Equation follows:

_{100}^{257}\textrm{Fm}\rightarrow _{98}^{253}\textrm{Cf}+_2^4\alpha

The nuclide formed is _{98}^{253}\textrm{Cf}

2) For beta-minus decay

In this process, a neutron is converted into a proton and an electron.

Equation follows:

_{98}^{253}\textrm{Cf}\rightarrow _{99}^{253}\textrm{Es}+_{-1}^0\beta

The nuclide formed is _{99}^{253}\textrm{Es}
