Answers
Answer:
1)Evaporation causes cooling but at the same time transfer of energy take place. The surface of the substance at which Evaporation is happening, get cooled. ... This increase in energy of surrounding increase the humidity content in air and also heat containt.
2)In classical physics and general chemistry, matter is any substance that has mass and takes up space by having volume.
3)A matter exists in solid state because of greatest force of attraction between its particles which makes the particles closely packed. A matter exists in liquid state because of less force of attraction between its particles than a solid, which makes the particles closely packed but allow to slide over one another.
4)There are four states of matter common in everyday life — gases, liquids, solids, and plasmas. However, there is also a fifth state of matter — Bose-Einstein condensates (BECs), which scientists first created in the lab 25 years ago.
5)the higher the temperature of the substance the greater the kinetic energy of the molecules at its surface and therefore the faster the rate of their evaporation.
