which option below best explains why the second law of thermodynamics is
not violated when heat flows from a cold freezer and into the much warmer
room?
o
a. the spontaneous flow of heat from a cool area and into a warmer
area is allowed.
o
b. the flow of internal energy out of the freezer is balanced by the
flow of energy into the room.
o
c. the electric motor on the freezer does work to remove the heat
from inside the freezer.
o
d. the freezer and room are not an isolated system, since electrical
energy flows in.

Classify each possible hypothesis about a medicinal aloe vera plant as falsifiable or non-falsifiable. aloe vera gel is the best natural skin moisturizer. aloe vera gel can heal wounds by boosting cell renewal. aloe vera juice tastes better than carrot juice. drinking aloe juice can reduce the risk of lung cancer.

Which best describes the difference between internal and thermal energy?

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
