Answer:
Due to vaporization
Explanation:
When water is converted into its vapour it absorbs heat from the surroundings. That heat is converted into the kinetic energy of vapour molecules. Due to this heat of the surroundings is lost and ambient temperature is reduced.
Over 10 crore household toilets have been built since Swachh Bharat was launched in 2014, but behavioural change still remains the key issue
Roshani Bhandari takes short, quick steps and disappears behind shrubs near a natural spring in her village in Uttarakhand’s Uttarkashi district. After answering nature’s call, the 48-year-old starts her km-long trek back home. Like other families in her village of Malna, Roshani has a toilet at home — one she seldom uses. “The toilet at home has no water. Sometimes, we store water in cans but it is not enough for the entire family. It’s easier in the open where water is readily available.”
Water-scarce Malna was among Indian villages that saw toilets being built at an unprecedented pace under Swachh Bharat Mission (SBM). From a mere 37,112 toilets in rural areas of Uttarakhand in 2014, the number now stands at 4,86,362. All 35 families in Malna have had a toilet since 2015, but lack of water means not everyone is using these. It’s the same story in Kharwada village in Rajasthan’s Sirohi district, where toilets without water are being used to store discarded items. Both Rajasthan and Uttarakhand were declared open defecation-free as early as 2018.
