Ответ:
The change in entropy of the carbon dioxide is
kilojoules per Kelvin.
Explanation:
By assuming that carbon dioxide behaves ideally, the change in entropy (
), measured in kilojoules per Kelvin, is defined by the following expression:
Where:
If we know that
,
,
,
,
and
, then the change in entropy of the carbon dioxide is:
The change in entropy of the carbon dioxide is
kilojoules per Kelvin.

melting point is a physical property of matter because when a substance melts, it changes state from a solid to a liquid but is still the same substance.
melting point is the temperature at which a substance changes from a solid to a liquid state. it is a physical property because measuring melting point does not change the identity of the substance.
a potassium ion will form a 1+ charge because it will have more protons than electrons.
the electrons would repel each other because they have the same charge.
