Answer: Collisions between gas particles are inelastic.
Explanation: Kinetic Molecular Theory explains the basic relation between the temperature and the speed of the gaseous molecule . From this theory itself, ideal gas equation was born.
the incorrect postulates among the given is that the 'Collisions between gas particles are inelastic' because during collision, the gas molecules collide with one another as well as with the walls of the container .
Thus there is no loss of kinetic energy in the collision phenomenon .
It is also correctly given that Gas particles are small and spherical with an insignificant volume and the motion of gas particles is constant and random.
like gold,

Explanation:
When gold is hammered it "squishes". Iron Pyrite is
known as "Fool's Gold". It is not..........

Gold is a malleable metal, able to deform without breaking when hammered. On the contrary, Iron Pyrite or 'Fool's Gold' is brittle; it shatters when struck due to its lack of malleability.
Gold is known as a malleable metal, which means it can be hammered or bent into different shapes without breaking. In contrast, Iron Pyrite, often known as 'Fool's Gold', is brittle, meaning it will shatter or break when struck by a hammer.
Malleability is a physical property of metals that allows them to be hammered or rolled into thin sheets. Gold is one of the most malleable metals and can be hammered into extremely thin sheets.
On the other hand, a brittle material like Iron Pyrite lacks this property of malleability. Instead of deforming under stress, it will fracture, this is why it shatters into many pieces when struck.

When the temperature of a substance decreases, the average kinetic energy of its particles also decreases. This is because the temperature of a substance is proportional to the average kinetic energy of its particles. The slower the particles move, the lower the kinetic energy.
The question refers to the relationship between the temperature of a substance and the average kinetic energy of its particles. According to the kinetic-molecular theory, the temperature of a substance is proportional to the average kinetic energy of its particles. When the temperature of a substance rises, the particles vibrate more in solids or move more rapidly in liquids and gases, indicating an increase in kinetic energy. Conversely, if the temperature decreases, the kinetic energy also decreases, and the particles move more slowly.
For instance, when the temperature of a gas increases, its average kinetic energy increases, more molecules have higher speeds and fewer molecules have lower speeds. The distribution shifts towards higher speeds overall. If the temperature decreases, the opposite happens: the average kinetic energy decreases, more molecules have lower speeds and fewer molecules have higher speeds. The distribution shifts towards lower speeds overall.

The moon surface isvisible to an observer on earth due to the gravitational force that attracts themoon to the earth. The more massive the body is, the more the smaller body isattracted to the larger body. We can only see the side of the moon due to thespeed at which the moon rotates.
The answer is: 3) 7.64 days.
The most stable isotope of radon (Rn) is radon-222 with a half-life of 3.82 days.
After first half life (3.82 days) = 0.5 · 200 g.
After first half life (3.82 days) = 100 g of radon-222.
After second half life (7.64 days) = 0.5 · 100 g.
After second half life (7.64 days) = 50 g of radon-222.
Half-life is the time required for a quantity (in this example number of radioactive nuclei of radon-222) to reduce to half its initial value and is independent of initial concentration.
parasitism
B.
amensalism
C.
commensalism
D.
symbiosis
Answer: C: commensalism please give me hearts and stars because the answer is right!!
Explanation:
The relationship between the clown fish and the deadly sea anemone can be classified as commensalism. Though the sea anemone’s tentacles are covered with thousands of nematocysts (tiny, venomous harpoons), the clown fish is protected by a thick coat of mucus and is not harmed by the anemone’s venom. The clown fish is therefore protected from predators and is also able to get leftover food from the anemone's meals. Since the clown fish ultimately benefits from this arrangement and the sea anemone neither benefits nor suffers because of the clown fish, the relationship is commensalistic.
The clown fish and the sea anemone exhibit a mutualistic relationship, where both organisms benefit. However, among the options provided in the question, the most accurate is 'symbiosis', which broadly denotes a close, long-term interaction between different biological species.
The symbiotic relationship between the clown fish and the sea anemone is referred to as mutualism. This term, which is missing from the options, indicates a relationship in which both organisms benefit. The clown fish is protected from predators and has access to food remnants, whereas the sea anemone gets cleaned by the clown fish, which removes parasites and debris. Among the options provided, the closest would be symbiosis (option D), as it describes a close, long-term interaction between different biological species, which can include mutualism, commensalism, and parasitism.
