Water Doesn't Always Boil at 100 Degrees
Description
Discover how air pressure influences the boiling point of water and how it is possible to boil water even at room temperature by creating a vacuum. The video demonstrates the direct physical connection between external pressure and the energy required for water molecules to transition into a gaseous state.
Original title
מים לא רותחים תמיד ב-100 מעלות
גלו כיצד לחץ האוויר משפיע על טמפרטורת הרתיחה של המים וכיצד ניתן להרתיח מים אפילו בטמפרטורת החדר באמצעות יצירת ריק (ואקום). הסרטון מדגים את הקשר הפיזיקלי הישיר בין הלחץ החיצוני לבין האנרגיה הדרושה למולקולות המים כדי להפוך לגז.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
