What is the minimum possible temperature (absolute zero), and what happens to the energy of particles at this temperature?
- A$-273\,^{\circ}\text{C}$; particles have least kinetic energy
- B$-273\,^{\circ}\text{C}$; particles have zero gravitational potential energy
- C$0\,^{\circ}\text{C}$; particles have least kinetic energy
- D$0\,^{\circ}\text{C}$; particles have zero gravitational potential energy
