Which cup has more thermal energy?

dybincka [34]

Question: Which cup has more thermal energy?

A. 2 liter cup of milk

B. 1 liter cup of milk

Answer: A. 2 liter cup of milk

Explanation:

We have milk in both of the containers. The milk in both containers is the same temperature, so we will have to measure the amount of molecules. The amount of molecules makes it warmer, and if it is warmer, that is more energy. 2 liters have more thermal energy than 1 liter, because it has more molecules.

Our answer is 2 liter cup of milk.

Sergio039 [100]

Answer:

The triglyceride made from glycerol, myristic acid, palmitic acid and cis-oleic acid is shown in the attached pictures.

Explanation:

A triglyceride or triacylglyceride is an ester derived from glycerol and three fatty acids. The fatty acids of this exercise are myristic acid, palmitic acid and oleic acid.

A fatty acid is a biomolecule of lipid nature formed by a long linear hydrocarbon chain, of different length or number of carbon atoms, at the end of which is a carboxyl group.

The myristic acid has a carbon chain of 14 carbon atoms with a carboxyl group at one end.

Palmitic acid has a carbon chain of 16 carbon atoms with a carboxyl group at one end.

Oleic acid has a carbon chain of 18 carbon atoms with a carboxyl group at one end and a double bond at position 9.

Triglyceride is formed by the esterification of the glycerol oxidrile group and the carboxyl acid group.
