No - ice can go straight to vapor without first melting. The process is known as "sublimation".

What degree does water boil and melt at?
Water boils when the temperature gets to 212 degrees Fahrenheit or 100 degrees celsius. Water does not melt. It changes into a vapor-like fog and disappears into a gas.
How does melting point change as the water content of rocks increases?
The presence of the water in its vapor phase causes the melting point to decrease and the rock to melt and absorb the vapor.
What are the steps of water vapor to sleet?
The water vapour in the atmosphere condense to form clouds. It may precipitates in the form of sleet.
Would ice cubes melt in hot water first or will the ice cubes freeze the water first?
If you put ice cubes in a bowl or whatever of hot water, the ice cube is sure to melt when put so says science.
Can Physical changes change back into their original form?
I say yes becuse for example if you freeze water it will turn into ice then melt then melt back into water.ps add jj serrano on facebook
Is when ice changes into water vapor it must melt first?
Yes. In the case of ice, it should melt first, convert to liquid water and then change to water vapor. There is big difference in the temperature for the melting point of ice and boiling point of water.
How does snow changes to form water vapor?
Snow can melt and turn into water and evaporate, and then the water turns into water vapor.
What degree does water boil and melt at?
Water boils when the temperature gets to 212 degrees Fahrenheit or 100 degrees celsius. Water does not melt. It changes into a vapor-like fog and disappears into a gas.
How does ice to water to water vapor?
Heat causes the ice to melt into water and the water evaporates into vapor.
How does snow change to water vapour?
Snow changes into water vapor because it's left outside and eventually it will melt because it's not always FREEZING cold outside and the snow or ice will melt.
Three examples of physical changes are?
liquid to solid, solid to liquid, gas to liquid that sort of thing
When water changes to ice what kind of changes has occurred?
because it melt
How does melting point change as the water content of rocks increases?
The presence of the water in its vapor phase causes the melting point to decrease and the rock to melt and absorb the vapor.
What will happen if you leave boiling water ice and tap water for a day in separate cups?
The boiling water will evaporate (turn to vapor). The ice will melt (turn to liquid) and then begin to evaporate (turn to vapor). The tap water will begin to evaporate (turn to vapor).
What happened to water vapor when earth formed and cooled?
When the earth formed and then cooled, the water vapor and water froze forming the glaciers. The glaciers later started to melt which formed lakes, rivers, and oceans.
What happens if there is a lot of water present in the magma of a volcano?
The large amount of water would first increase the amount of magma, as it make it easier to melt rocks. Then the water vapor would help cause explosive eruptions.
What process occurs as pieces of ice sit in the sun?
the ice can melt and turn to water, or sublimation can occur and the ice turn to water vapor.
