Water vapor releases heat as it condenses on the skin, which damages the tissue.
2.WHAT IS AN EXAMPLE OF A SUBSTANCE
EVAPORATING✔✔ Water turns to steam when it hits a hot stovetop.
3.AURORAS ARE BURSTS OF LIGHT THAT HAPPEN WHEN CHARGED PARTICLES FROM THE SUN

ATMOSPHERE.- WHICH PHYSICAL SCIENCE IS BEST SUITED EXPLAIN THE INTERACTIONS OF
THE CHARGED PARTICLES WITH EARTH’S MAGNETIC FIELD✔✔
Chemistry.
4.THE OBSERVATIONAL BALLOON IS FILLED WITH HELIUM AND VENTED TO THE ATMOSPHERE.

THE DAY AND NIGHT CYCLE. THE SCIENCE BEST FOR STUDYING THE DAILY WARMING AND
COOLING OF THE ATMOSPHERE IS .
Earth science
5.WHICH PHYSICS TOPIC WOULD BE TH EMOST IMPORTANT IN CHEMISTRY✔✔
