Question

Which of the following statements is true?

The boiling point of a substance is dependent of volume.
During sublimation, a plasma changes directly into a solid.
The nucleus of an atom is made of protons and neutrons.
Electrons orbit the nucleus of an atom in straight lines.

Answer 1

Only one: the nucleus of an atom is made up of protons and neutrons.
Why others are false:
Boiling point of a substance is not dependent on the volume because it’s a intensive property.
During sublimation, a solid changes directly into gas.
Electrons orbit the nucleus of an atom in circular orbits (kinda unsure of this one.)
