Answer:
Final pressure, P2 = 362.26 kPa
Explanation:
Given the following data;
Initial volume = 32.5 Liters
Initial pressure = 45.7 kPa
Final volume = 4.1 Liters
To find the final pressure, we would use Boyle's law;
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
Substituting into the equation, we have;
Final pressure, P2 = 362.26 kPa

Explanation:
Root hairs are found in the plant it is a hair-like structure present on the surface of the root tip and Root hairs have large surface area that increase the absorption rate of water and minerals.
Water is absorbed by root hair cells through the process called Osmosis and Minerals ions is absorbed root hairs by the process called active transport.
The function of root hair is to collect the minerals and waters present in the soil and then transfer these nutrients and water through roots to different parts of the plant.
Answer:
F,T,T,F
Explanation:
1)false-(its a covalent bond)
A water molecule is formed when two atoms of hydrogen bond covalently with an atom of oxygen.
2)True-(water is a polar molecule)
Water is a polar molecule because the positive end attracts particles of negative charge.
3)True
water dissociates to form hydrogen ions (H3O+) and hydroxide (OH-) ions
4)false
Lower pH number means stronger acid, higher pH number means stronger base.
