Answer: At very low temperatures, gases expand less for a given pressure change than they do at high temperatures.
Explanation:
True, if you have rough surface the more friction you have. The More slipery, less friction.
Answer:
<h2>111 kPa</h2>
Explanation:
The new pressure can be found by using the formula for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the new pressure
We have
We have the final answer as
<h3>111 kPa </h3>
Hope this helps you
Answer:
Galena
Explanation:
Galena is also known as lead glance. This is a natural mineral of the form lead(II) sulfide. It is one of the most important ore for lead. It is widely found and is mainly distributed in sulfide minerals.
Galena can be easily scratched by finger nails. It has black streak and have a metallic luster. Galena have cleavage. It usually occurs as cubic crystals.
Yes, it is a liquid because a solid is a state of matter with a fixed volume and shape; and Gases take both the shape and the volume of their container; and liquid is the one that takes the shape of their container but not necessarily the volume.
