A phase change is when the molecules heat up and move faster. The process of heating up molecules will turn a solid into a liquid and then into a gas as the molecules start to move faster and start to have more space between them.

Answer:
Hi
2-methyl-1-propanetiol is found in alcoholic beverages. It is a food additive, and is also found in guava, milk, cooked beef, cooked pork and beer. It is also used as a flavoring. A dose of 7168 mg / kg produces muscle weakness, ataxia, cyanosis. An intraperitoneal dose of 917 mg / kg can cause nervousness and a feeling of spastic paralysis. In the attached file is the scheme.

Answer:
The P-H bonds are more polar than the N-H bonds.
Explanation:
Phosphine is a polar molecule with non-polar bonds. The phosphorus atom is bonded to three hydrogen atoms and the phosphorus atom has a lone pair of electrons. Since hydrogen and phosphorus are equal in electronegativity, it implies that they attract the shared pairs of electrons the same amount,hence bonding electrons are shared equally making the covalent bonds non-polar.
The lone pair of electrons on phosphorus causes the molecule to be asymmetrical with respect to charge distribution this is why the molecule is polar even though the are non-polar bonds in the molecule.
Looking at the values of electro negativity stated in the question, one can easily see that the difference in electro negativity between nitrogen and hydrogen is 0.9 while the difference in electro negativity between phosphorus and hydrogen is zero. It is clear that NH3 is naturally more polar than PH3 since each individual N-H bond in NH3 is a polar bond while the individual P-H bonds in PH3 are nonpolar.
