The magnet will be a useful tool to pick the paper clips because the magnet can attract the paper clips.
<h3>
Attraction of magnets</h3>
The like poles of magnets repel while unlike poles of magnets attracts. Magnets attracts irons or metallic materials.
The paper clips are mettalic or made of iron and hence the magnet will attract them.
There we can conclude that the magnet will be a useful tool to pick the paper clips because the magnet can attract the paper clips and will help to gather them together for easy picking.

According to the combined gas law: (P₁*V₁)/T₁=(P₂*V₂)/T₂, where P is the pressure, V is the volume and T is the temperature.
P₁=0.4 atm = 40530 Pa
V₁=21.7 L = 0.0217 m³
T₁=252 K
P₂=2 atm = 202650 Pa
T₂=323 K
V₂=?
We need to solve for V₂:
(P₁*V₁)/T₁=(P₂*V₂)/T₂
(T₂*P₁*V₁)/T₁=P₂*V₂
(T₂*P₁*V₁)/(T₁*P₂)=V₂, now we plug in the numbers and get:
V₂=0.00556 m³, and we can see that with increased temperature and pressure the volume V₂ has decreased.
When we transfer V₂=0.00556 m³ to liters we get that 0.00556 m³=5.56 L. That can be rounded up to V₂=5.6 L.
The two biomes that have the least precipitation (rain) would be the desert and tundra
Answer:
Unit conversion is very important because the rest of the world other than three countries uses the metric system. So, converting units is important in science because it uses the metric system. The metric system is measurements like cm, m, l, mL, etc...
Explanation:
Units can: Help to show another person the exact amount you have. Assist in solving a mathematical problem, especially in chemistry, where you can follow the units to get to the answer. Show which measurement system the person is using (i.e. metric or standard)
