Answer:
Correct option: Vapor pressure increases with temperature
Explanation:
Vopor pressure: it is defined as the pressure exerted by gaseous molecule on the surface of container and vopor is produced by only volatile component of solution.
Kinetic energy of molecule depends on the temperaure of sample or molecules when temperature is increased then its kinetic energy also increased and as kinetic energy increases then the chances of molecule going into vapour phase increases thereby increasing the vapour pressure.
hence Vapor pressure increases with temperature

Explanation:
Pioneer plants are to plants species that appear first in virgin land – such an after a volcanic eruption. They are mainly lower plants such as lichen, fungi, and noses. These species can grow on rocks and break them down over time to form soil. This is due to the fact that the plants have very shallow roots that can even grow in the small crevices of rocks and can draw water from the atmosphere – moisture. This releases the nutrients in the rocks and makes them available to higher plants that have deeper roots. The ecology of the region will ultimately be succeeded by a climax community over time, mainly dominated by tree species.
Percentage recovery gives us an idea of the amount of pure substance recovered after the chemical reaction. Percentage recovery can be more than 100 % or less than 100 %. Usually, in any experiment performed the weight percentage recovery will be less than 100. Percent recovery values greater than 100 show that the recovered compound is contaminated.
Amount of acetaminophen initially taken = 350 mg
Amount of acetaminophen obtained after recovery =185 mg
= 
= 52.9%
