Which state of matter consists of particles that can be partially compressed? Gas Liquid Plasma Solid
son4ous [18]

Answer: Option (b) is the correct answer.

Explanation:

In liquid state, particles do have kinetic energy that helps in partially overcoming the intermolecular forces between the molecules. But still the particles are close together and they are able to slide past each other.

So, when we apply pressure on a liquid then its molecules partially gets compressed.

On the other hand, molecules of a solid are held together by strong intermolecular forces of attraction. Hence, they have definite shape and volume. As a result, solids do not get compressed.

In gases and plasma state of matter, molecules are gar away from each other. So, they are able to get completely compressed when a pressure is applied.

Thus, we can conclude that liquid is the state of matter which consists of particles that can be partially compressed.

Iron-60 Express your answer as an isotope.
lys-0071 [83]

Isotopes are variants atoms of the same element, having same number of atomic(proton) number but different number of neutrons and mass number.

Considering iron-60

  • The atomic number which also equals the number of protons for the element iron as can be seen on the periodic table is 26
  • The name  iron-60 also tells us that this particlar  isotope's mass number is 60.  
  • The chemical symbol for Iron  is Fe

Now expressing  as an isotope iron-60 becomes   ⁶⁰₂₆Fe ( very unstable )

Other stable isotopes of Iron include   ⁵⁴₂₆Fe , ⁵⁶₂₆Fe, ⁵⁷₂₆Fe and ⁵⁸₂₆Fe
