Is this ice forming at the wall of a Legazpi home on cold days? Kuya Kim explains
A family in Legazpi, Albay was puzzled after they saw white, ice-like substance start forming on their wall on cold days.
In Kuya Kim's report on "24 Oras," Thursday, Jome Añonuevo said that his children were the ones who first spotted this.
"Ang mga anak ko nang gumising sila madaling araw, nakita 'yung yelo dito sa pader namin. Malaki, makapal. Ngayon lang namin na-experience 'yan," he said.
"Nalulusaw naman siya sa kamay," Jome continued, adding that it melts up when the heat is strong, leaving only a small amount on their wall.
Jome sent the video to his brother, who uploaded the clip on social media.
"Nung pinasa po 'yun sa 'kin ng kapatid ko nagulat po ako," Diome said.
The family suspects that it was caused by the cold weather because they don't have a freezer placed near the wall.
"Sabi ko baka natural lang 'to. Kaninang umaga, mga bandang alas tres ng madaling araw, super lamig po," Jome said.
However, according to Philippine Atmospheric, Geophysical and Astronomical Services Administration weather forecaster Aldczar Aurelio, it is not possible that it was ice that formed on the family's wall.
"'Yung minimum temperature sa Legazpi ay naglalaro sa 24°C. Malabong mabuo ang isang yelo doon sa pader," he said.
It was also not frost, which forms in cold places like Benguet.
"Nangyayari ang frost kapag ang isang surface ay aabot sa temperature na ideally 0°C o freezing temperature para maging yelo siya," he said.
According to chemist Janir Dakutan, it is possible that the white stuff was efflorescence, a deposit of salt formed on the surface of concrete.
"May mga salts, maaari itong mag-dissolve sa water, nagfo-form siya ng solution. 'Pag itong mga solution na ito ay nasa loob ng semento, ang tendency nito ay lumabas sa semento at pupunta 'yan sa surface," he said.
"Makikita natin nagmo-moist 'yung semento, and then mag-e-evaporate 'yung water, so magda-dry. Naiiwan 'yung residue nung salt, 'yan 'yung puting substance na nakikita natin."
