He says HI, I'M TEACHER
ALDO AND I'M HERE TO TALK TO YOU
ABOUT CONDENSATION.
THE OTHER DAY A STUDENT ASKED
ME, WHY DID THEY SEE THEIR
BREATH ON A COLD WINTER DAY?
WE'VE DONE IT, WE'VE GONE
OUTSIDE ON A COLD WINTER DAY
AND HAVE SEEN THE FOG FROM OUR
BREATH.
WHY DOES IT HAPPEN?
WELL THAT HAS EVERYTHING TO DO
WITH CONDENSATION.
AS WATER VAPOUR
LEAVES YOUR BODY AT 37 DEGREES
CELSIUS, IT GOES OUTSIDE AND IT
HITS THE COOL ATMOSPHERE
TEMPERATURE AND IMMEDIATELY
CONDENSES IN TO WATER DROPLETS.
THAT'S THE FOG YOU SEE
AND THAT'S CONDENSATION.
