Question

2. Pressure and temperature determine the state of a substance. Explain this in detail.

Answer 1

Answer:

yes

Explanation:

coz...by increasing pressure. the kinetic energy of atom becomes low so that gas comes to liquid and liquid comes to solid

And by increasing temperature... kinetic energy of atoms becomes very high so that the intermolecular force of attraction becomes low...so solid becomes liquid and liquid becomes gas..

I hope you are satisfied with my answer..

Answer 2

preasure and temperature determine the state of the substance as a substance will change its state from solid -->liquid-->gas or vice verca

kinitic energy increases at higher temperature and at lower pressure which helps in change of state

example:water waper changes its state from gas to liquid when temperature decreases and pressure increases

a substance changes from solid-->liquid-->gas when temp increases and preassure decreases or vice verca for gas to liquid
