Is a mammal an endothermic organism?

Polar bear, like all other mammals, are warm blooded. The terms exothermic and endothermic do not apply to species of animals, they are used to describe chemical reactions (exothermic reactions generate energy, whereas endothermic reactions require energy to make them happen).


What are differences between endothermic and exothermic reactions examples?

The main differences between exothermic reactions and endothermic reactions are: Exothermic reactions are reactions that give off energy (light, electrical or mainly heat), causing the surroundings to warm up. Endothermic reactions are reactions that absorb energy, causing the surroundings to cool down. The products of an exothermic reaction have less energy, or less total enthalpy, than of it's reactants. This is due to the reactants containing more stored energy because energy from external sources is not required. This also gives the products more stability because in order to achieve a reversible reaction and break the chemical bonds of the products, you will need to apply more energy to it. The opposite is for endothermic reactions. The products of the reaction have a greater total enthalpy of the reactants, causing the reactants stored energy to decrease. This produces less stable products that need less energy to break their bonds in a reversible reaction. Finally most exothermic reactions are spontaneous, where as most endothermic reactions are not spontaneous as they generally need energy applied to them before they start.


Which states of matter will pascal's princapal apply?

liquid and gas, the two states of matter that its particles can move past one another


Is melting of iron in furnace exothermic?

Neither endothermic nor exothermic. These two terms apply to chemical reactions, wether they require or produce energy (heat). Melting iron isn't a chemical but a physical reaction, a change of phase, solid to liquid. Iron is solid at room temperature, we heat it to melt it, so heat is added (which is the same as the principle of endothermic, heat is absorbed, it must be heated)


Does pascal's principle apply to all states of matter?

Yes, Pascal's principle applies to all states of matter. It states that a change in pressure applied to a fluid is transmitted uniformly in all directions, regardless of the state of matter of the fluid.


How does the kinetic theory of matter relates to the Alchemist's water distillery and apply it to each step of the process?

The Alchemist needs to apply heat to the particles to change their kinetic energy and make them change states of matter.


Does liquid matter or solid matter take up more space?

Liquid matter typically takes up more space than solid matter because the particles in a liquid are not as closely packed together as in a solid. This is why liquids have a fixed volume but can take the shape of their container.


Is an exothermic reaction will produce heat and will be reabsorbed to increase the rate of reaction?

Have you heard of Haber-Bosch process of production of ammonia. This is an example of the question you asked. If we apply the required heat in the beginning of the reaction we do not need to apply it again as its exothermic reversible reaction and will use the heat to continue the reaction. But the rate of reaction is not increased.


Does the kinetic theory of matter relate to solids liquids and gases?

Kinetics apply to all matter(or actually anything with mass), regardless of the state that matter is currently in. Think of it like this, a drop of water, and an ice cube are both dropped from the roof of a building. They are the same matter but in different states. Because they are both moving, both have kinetic energy regardless of being in different states.


How does the law of the conversation of mass apply to chemical reactions?

the law of conservation of mass states that matter can neither be created nor destroyed. so when a chemical reaction takes place, no matter is being destroyed. the mass of the reactants must equal the mass of the products.


Why are some rights unalienable?

Some of these rights are unalienable because no matter who you are these rights apply to you. No matter the circumstances.
