Why gases condense when they are cooled?

The expansion of gases takes place because of kinetic energy provided by heat which excites the molecules and causes them to move further apart. On cooling the atoms in a gas lose their energy and slow down coming closer together.

We can explain this in a molecular level. We know that the difference between a gas and a liquid of the same composition is how fast their molecules are moving. So given a gas, their molecules are farther and faster when moving, but when they are cooled their bulk kinetic energy decreases. In other words their molecules start to move closer and move slower until it behaves more like a liquid molecule. This is the time when gases condense

The axon joins the cell body at a cone-shaped elevation called the?
astraxan [27]

Answer:

B. axon hillock

Explanation:

The axon hillock is the junction where the cyton connects with the axon. There is only one axon hillock in the neuron and it is a triangular depression of cell boy to the axon. The axons receives impulse from cyton carry to the different parts of the body. The axon hillock is also called initial segment. Because action potential starts here.

Myelin sheath is the cover or layer around the axon and helps in saltatory movement of impulse. The propagation of impulse is fast in myelinated neurons than the non-myelinated neurons.

The neurolemma is the neural membrane of the neurons. It is like the plasma membrane of the cell. The outer covering of neurons is called neurilemma.

Axon collateral is the end of the axon where axon terminals arise. They carry impulse and transmit to the synapse.

State where bile is synthesized and explain the role of bile in digestion and excretion
earnstyle [38]
Liver secretes bile which is then stored in gall bladder. Bile enters the duodenum via the bile duct. Bile emulsifies lipids, transforming large lumps of lipids into tiny droplets, which provide a larger surface area for digestion. This allow lipid digestion to proceed more rapidly. Bile contains bile acids, which are critical for digestion and absorption of fats and fat-soluble vitamins in the small intestine.Many waste products, including bilirubin, are eliminated from the body by secretion into bile and elimination in feces.

ValentinkaMS [17]

Answer:

The correct answer is B. In the human eye, the greatest amount of refraction occurs when the light passes from the air into the cornea.

Explanation:

The ocular refraction refers to the refraction that occurs in the light coming from the objects when crossing the different parts of the eye, causing the images to concentrate on the retina.

When the light rays, after crossing the cornea and the lens, are projected on the retina at a single point creating a clear image that is transmitted to the brain for processing, we talk about normal refraction.
