Question

If you have a 1 L container of milk and a 2 L container of milk sitting at room temperature, the 2 L container of milk will have more: (Select all that apply)

a
mass
b
temperature
c
thermal energy
d
kinetic energy

Answer 1

Answers: a and c.

- a (mass): yes — 2 L of milk contains more mass.
- b (temperature): no — both are at the same temperature.
- c (thermal energy): yes — thermal (internal) energy scales with the amount of substance at a given temperature, so the larger volume contains more internal energy.

Note on d (kinetic energy): if by "kinetic energy" you mean the total microscopic kinetic energy of all the molecules, then the 2 L sample has more (because it has more molecules even though the average per molecule is the same). If you mean macroscopic kinetic energy of the containers (bulk motion), both are the same (usually zero if they’re just sitting).
