Question
Fill in the blanks with the correct word/s from the bracket.
Ice on absorption of heat converts to ‘X’ a process called ____ [vaporization / melting]. ‘X’ changes to water vapour on ____ [heating / cooling]. Water vapour changes back to ‘X’ on ____ [freezing / condensation]. The constant temperature at which ice changes into ‘X’ is called its ____ [fusion point / melting point / boiling point].
Solution
Ice on the absorption of heat converts to ‘X’ a process called melting. ‘X’ changes to water vapour on heating. Water vapour changes back to ‘X’ on condensation. The constant temperature at which ice changes into ‘X’ is called its fusion point.
