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).

Answer 1

Ice on 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.
