Can a tank of oxygen gas ever be half empty? explain

Answers

No, it is practically very unlikely situation. Oxygen is a gas and gas has no shape it occupies the shape of the container. moreover, according to the kinetic theory of gases, the particles of gas move in random motion occuping the space. The particles move randomly and keep on colliding with each other. Therefore, it is not correct to say that a tank of oxygen gas can ever be half empty.
The answer is yes. The compacted air moves to the sifter bed channels. The strainer bed channel assumes an imperative part, as the gadget expels the nitrogen from the air. After air is first compacted in the concentrator, it is constrained into the primary strainer bed. Oxygen is sent into the item tank.

Which changes occur in the composition of the earths layers from the surface to the core

Answers

Answer:

B. The material is cooler and denser.

Explanation:

The earth is made up of three layers, the crust, the mantle and the core. Each layer has different characteristics and temperatures, becoming warmer and less dense as it approaches the core.

Man has never reached the core of the earth, but the study of the internal structure of the planet is possible thanks to the studies of geophysicists, who are dedicated to the study of seismology. They observe the phenomena of seismic waves and rely on apparatus to define the characteristics of each layer.

  • Earth's crust: Most superficial layer, relatively thin structure and very rocky.
  • Mantle: Located below the crust, it has solid properties.
  • Core: Earth's warmest, least dense layer.
The mantle is the least hottest
