Explanation:

The first law of thermodynamics states that:

where

U is the internal energy of the gas, which represents the sum of the chemical and thermal energy stored in the atoms and molecules of the gas

represents the variation of internal energy

Q is the heat absorbed by the system

W is the work done by the system

So, the sum of the chemical and thermal energy stored in atoms and molecules is represented by U, the internal energy.

asthenosphere and convection

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone
