Heating is a process that involves the transfer of thermal energy from a hot object to a cooler object. When a substance is heated, its particles gain energy and move faster, causing changes in its physical state. In this question, we are asked to identify the change that can occur by heating among the given options.
Liquid water changes to ice
- This is not a change that occurs by heating. It is the opposite process, where water is cooled and its particles slow down, causing the formation of ice crystals.
Water vapor changes to liquid
- This is a change that occurs by heating. When water vapor, which is the gaseous form of water, is heated, its particles lose energy and slow down, causing them to come together and form liquid water droplets.
Ice changes to liquid water
- This is a change that occurs by heating. When ice, which is the solid form of water, is heated, its particles gain energy and start moving faster. This increase in energy causes the ice to melt and convert into liquid water.
Water vapor changes to ice
- This is not a change that occurs by heating. It is the opposite process, where water vapor is cooled and its particles slow down, causing the formation of ice crystals.
Therefore, the correct answer is option 'C' - ice changes to liquid water.
