10.
Which of the following best describes the application of the first law of thermodynamics in a star?
a)
The energy produced in the core of a star is lost to space and does not contribute to the star's luminosity.
b)
The energy produced through nuclear fusion in a star is converted into heat and radiated as light, maintaining energy conservation.

11.
Which of the following describes the second law of thermodynamics?

For a spontaneous process, the entropy of the universe increases.
b)
Heat disperses faster that it is created.
c)
Heat travels from cold to hot.
d)
All women have a body temperature 2 degrees lower than their male counterparts. This explains why they are always cold.

How does the second law of thermodynamics explain the overall evolution of the universe?
a)
The universe will eventually reach a state of maximum energy concentration.
b)
Entropy in the universe is always decreasing, leading to an increase in order.
c)
Over time, entropy increases, leading to the eventual "heat death" of the universe.
d)
Energy in the universe is conserved but can transform between different types without affecting overall disorder.
