<h3>What is practical work?</h3>
In science, practical work refers to the art of conducting experiments in order to answer certain research questions. This could occur in a laboratory under controlled conditions or in the field.
In the physical sciences, most of the practical work is conducted in the laboratory under controlled conditions. However, some experiments in the biological sciences and most experiments in the social sciences are conducted outside the laboratory.

11. <span>Ionic compounds that dissolve in water conduct electricity because they break into ions that move freely.
12. </span><span>Solid metals are good conductors of heat and electricity.
13. </span>Molecular compounds that dissolve in water do not conduct electricity because no charged particles are present.
14. <span>Because the electrons in a molecule of hydrogen fluoride (HF) are more strongly pulled toward the fluorine atom, the molecule is polar.
</span>
15. A metal crystal consists of positively charged metal ions embedded in a "sea" of freely moving valence electrons.

<h3>A Werewolf</h3>
___________
Poem with Compound Words
------------------------------------------
whenever there's a full moon,
I cannot overlook,
some alterations in my ways,
and changes in my look.
my werewolf hair grows everywhere,
my werewolf teeth get long,
my eyesight gets much keener and
I'm muscular and strong.
I get to roam around outside,
the moonlight makes me howl,
these otherworldly sound effects
mean I am on the prawl.
I see the moon is round and full,
I'm moonstruck by the sight,
I've made some telltale changes-so, you'd best stay in tonight.

Pressure of Butane in the container at 135°C = 1.07 atm
Given:
The H°vap of butane is 24.3 kJ/mol.
starting out at 25 °C
Temperature at the end: 135 °C
2.3 atm of pressure
To Find:
The container's pressure
The perpendicular force per unit area, also known as the stress at a point within a confined fluid, is known as pressure in the physical sciences.
Equation of Clausius-Clapeyron
P2 = 1.07 atm and ln (P2/2.3 atm)
= - 24.3*110/8.31
The pressure in the container at 135°C (ΔH°vap ) is 1.07 atm
