Answer:
The internal energy of a system <u>is the sum of the potential and kinetic energies of the components</u>
Explanation:
Internal energy is defined as the sum of two types of energy: kinetic energy and potential energy.
Kinetic energy is defined as the sum of all the kinetic energies that each element has within a system with respect to its center of mass. It is caused by the movement of particles. Meanwhile, the potential energy is the energy that is associated with each of the interactions. Potential energy is associated with the constituents of matter, of the electrostatic energy of each atom that is inside the molecules.
The Bohr model is the basis for chemistry
Answer:
Explanation: Ethanol, CH3CH2OH, has the highest of the three boiling points because it has the strongest dipole–dipole forces between molecules due to hydrogen bonding. ... Dimethyl ether, CH3OCH3, has the second- highest boiling point because it has dipole–dipole forces between molecules.
Answer:
The nitrogen fixing bacteria are present in the soil and in the root of the plant in the form of microorganism. It changes the gases of the nitrogen from atmosphere into the component of the solid nitrogen which the plants uses in the soil.
The bacteria coverts the free nitrogen into the form of nitrogen compounds and it decomposes nitrogen compounds into the free nitrogen.
