Class 6 Science Curiosity A Journey through states of Water
If you are looking for Class 6 Science Curiosity A Journey through states of Water, then you are at the right place.
Q: What are the three states of water mentioned in the chapter?
A: The three states of water are solid (ice), liquid (water), and gas (water vapor).
Q: What is condensation?
A: Condensation is the process of conversion of water vapor into its liquid state.
Q: What happens when water vapor comes in contact with a cold surface?
A: When water vapor comes in contact with a cold surface, it forms water droplets through condensation.
Q: What is the process of conversion of a solid into liquid state called?
A: The process is called melting.
Q: What is the process of conversion of liquid into solid state called?
A: The process is called freezing.
Q: How can you change ice to its liquid state quickly?
A: You can change ice to its liquid state quickly by supplying heat to it.
Q: What conditions affect how fast water evaporates?
A: Conditions that affect evaporation rate include temperature, wind, exposed surface area, and humidity.
Q: Why do clothes dry faster on a windy day?
A: Clothes dry faster on a windy day because the increased air movement helps water evaporate faster.
Q: Why do clothes dry slowly on a rainy day?
A: Clothes dry slowly on a rainy day because the air already has high humidity, slowing down evaporation.
Q: What is the cooling effect associated with evaporation?
A: When water evaporates, it absorbs heat from its surroundings, causing a cooling effect.
Q: How does an earthen pot (matka) keep water cool?
A: Water seeps through the surface of the earthen pot and evaporates, imparting a cooling effect on the water inside.
Q: What is the water cycle?
A: The water cycle is the circulation of water between the Earth’s surface and atmosphere.
