Describe a stone falling off the tabletop in terms of both kinetic energy and potential energy?

Sitting on the table the stone has potential energy, relative to the ground, of weight times height, mgh. It has zero kinetic energy so its total energy is E = 0 + mgh. When it begins falling it loses potential energy (as it loses height) and gains kinetic energy ( as it picks up speed) so the sum stays the same as initially E = KE + PE = mgh. Just before it hits the ground all of its potential energy is gone and has been transformed into kinetic energy. So the kinetic energy at the bottom (1/2)mv^2 will equal the potential energy at the top.

What type if energy transfer when you eat a carrot?

Calories to jewls eventually. The calories have to be processed into fat and what not first, but then the muscles use them to create energy. So now you have it.


What are some examples of the first law of thermodynamics?

The first law of thermodynamics is the law of conservation of energy. Energy cannot be created nor destroyed, but only changed in form.For example when water turns a turbine in a hydroelectric power station. the loss in kinetic energy of the water is equivalent to the electric energy produced plus the waste heat, sound etc.Let a system absorbs Q amount of heat energy from the external source. As a result of this, let W be the work done by the system on its surrounding and ΔU be the change in the internal energy of the system. According to the law of conservation of energy,Q = ΔU + Wwhich is the mathematical statement of the first law of thermodynamics.Thus, the first law of thermodynamics may be stated as:The energy entering the system in the form of heat is equal to the sum of the increase in the internal energy of the system and the energy leaving the system in the form of work done by the system on its surroundings.

Why is the first ionisation energy of strontium larger than the first ionisation energy of rubidium?

Because, as we know that when we go across the period of the periodic table, the number of shells remain the same but the number of electrons and protons increases. So, Rb having its atomic number as 37 and Sr as 38, Strontium has got more nuclear charge as well as more electrons. As a result the first ionisation energy required to remove one electron is more in Strontium than Rubidium.


Why are the ionisation energy of isotopes the same?

The ionization energy of isotopes is the same because isotopes have the same number of protons in their nucleus, which determines the ionization energy. Isotopes differ in the number of neutrons they possess, but neutrons do not contribute significantly to the ionization energy compared to protons.


What is the relationship between ionization energy and the alkali metals?

There is no relation ship. They have the lowest ionization energies.


Why boron has a lower first-ionization energy than beryllium?

Because in Boron there is a complete 2s orbital and the increased shielding of the 2s orbital reduces the ionisation energy compared to that seen in Beryllium.


What is meant by the first ionisation energy of nitrogen?

The first ionization energy of nitrogen is the energy required to remove one electron from a neutral nitrogen atom to form a positively charged nitrogen ion. It represents the strength of the bond between the electron and the nitrogen atom.


Why the first ionisation energy of potassium is only a little less than the ionisation energy of sodium?

both are in the same period which accounts for closeness. they are nonetheless different because there are more protons in the nucleus which means electrons are brought closer to it so there is a higher ionisation energy or potential

Is the ionization energy of alkali metals larger or smaller than the alkaline earth metals in the same period?

It is about first ionization energy. It is less than alkaline earth metals.


What are the ionisation enthalpies of potassium and sodium?

The first ionization energy of potassium is 419 kJ/mol, while the first ionization energy of sodium is 496 kJ/mol. This means that it requires less energy to remove an electron from a potassium atom compared to a sodium atom.
