Holes in volcanic rocks illustrates a low pressure and rapid cooling environment(surface of the earth).
Explanation:
Holes in rocks are usually found in a special type of volcanic rock called pumice. The holes signifies a melt that has a lot of dissolved gases in them and they solidify rapid under surface temperature.
- Pockets of holes found in some rocks are as a result of trapped gases in cavities of a solidifying magma.
- The magma must erupt explosively so that the gases will not have enough time to escape.
- During an extrusive magma activity, the low pressure allows for dissolved gases to collects in cavities and magma cools rapidly around them due to the low surface temperature.
- The cavities left behind when the gases escape is the hole formed in volcanic rocks.

Answer : The correct option is, (c) use of a mobile and a stationary phase.
Explanation :
Chromatography : It is a separation process or technique of a mixture in which a mixture is distributed between the two phases at different rates, one of which is stationary phase and another is mobile phase.
Mobile phase : The mixture is dissolved in a solution is known as mobile phase.
Stationary phase : It is an adsorbent medium and It is a solid, liquid or gel that remains immovable when a liquid or a gas moves over the surface of adsorbent. It remains stationary.
Hence, a characteristic feature of any form of chromatography is the use of a mobile and a stationary phase.
Answer:
the answer would be ;B compare the volumes of the three cylinders
Answer:
3750 cm.
Explanation:
You multiply the three side measurements to find the volume.
25cm·10cm·15cm
375cm·10cm
3750 cm.
