Question

Explain the process of changing liquid to gas using an example. Make figure. How does the attractive forces between the molecules and their speeds change during this process ? Make a graph to show this process.

Answer 1

Water changes from liquid to gas when the heat energy overcome the hydrogen bonding between its particles.

Explanation:

• Water is an amazing substance and a universal solvent. It exists in three forms of matter Solid, liquid and gas.
• When we provide heat to the water, its particles start moving faster when they get heated up with that energy.
• The kinetic energy of the particles of water increase and they move apart breaking the hydrogen bonding force among them and turn into steam or gaseous state after reaching the boiling point.

Answer 2

Answer:

Water changes from liquid to gas when the heat energy overcome the hydrogen bonding between its particles.

Explanation:

Water is an amazing substance and a universal solvent. It exists in three forms of matter Solid, liquid and gas.

When we provide heat to the water, its particles start moving faster when they get heated up with that energy.

The kinetic energy of the particles of water increase and they move apart breaking the hydrogen bonding force among them and turn into steam or gaseous state after reaching the boiling point.
