exist as solid, liquid or gas?
Explain how en heliuified by applying pressure and
​

Answer 1

Answer:

intermolecular force of attraction by molecules decide

Answer 2

Answer:

Two factors determine whether a substance is a solid, a liquid, or a gas: The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance. Kinetic energy tends to keep the particles moving apart. The attractive intermolecular forces between particles that tend to draw the particles together.On applying pressure the gaseous particles come closer and start attracting eachother. ... So, while applying pressure to liquify the gas it is necessary to cool it to take away the heat produced during compression.
