Answer:
Rubber, or another insulator.
Explanation:
I'm not sure what the options are, but Sue would probably want an insulator so that the heat is trapped, keeping her hands cool.
Answer:
the answer is distillation
Explanation:
Sublimation is defined as a process in which solid state of a substance directly changes into vapor or gaseous state without undergoing liquid phase.
For example, naphthalene balls show sublimation at room temperature.
As this process does not cause any change in chemical composition of a substance. Hence, it is known as a physical process.
Similarly, when
sublimes readily at
. This shows change in physical state of carbon dioxide is taking place, i.e, from solid to gaseous phase.
Thus, we can conclude that when
sublimes readily at
then it means physical properties are usually associated with a compound that undergoes this kind of change.
