Question

Matter can be converted from one state to another and then brought back to the original state by making suitable changes in temperature and pressure.

• A. True
• B. False

Answer 1

The correct option is A True

• Matter can be converted from one state to another and then brought back to the original state by applying pressure and temperature.
• when we supply heat to the solid substance, the intermolecular force between the particles brokes down and converts into a liquid state. When we supply further heat, the liquid molecules gain a sufficient amount of energy and finally convert into a gaseous state.
• The gaseous substance formed above can be converted back into its original state ( liquid state) by applying high pressure and low temperature (Liquefying of gas).
  
• Matter can be converted from one state to another and then brought back to the original state by making suitable changes in temperature and pressure. Hence, the given statement is true.
