List three ways that energy could be lost between water and food

Chemistry

larisa [96]1 year ago

Work allows energy to be transferred from one object to another. To do work, an agent must exert a force on an object over a long distance.

When work is done, energy is transferred from the agent to the object, resulting in a change in the motion of the object (more specifically, a change in the object's kinetic energy).

What is energy?

Energy is essential to human society and has numerous health benefits. However, each energy source poses some health risks. This article examines the health consequences of each major source of energy, focusing on those with the greatest global impact on disease burden. The harvesting and burning of solid fuels, coal, and biomass have the greatest health consequences, primarily in the form of occupational health risks and household and general ambient air pollution. In the world's poorest households, a lack of access to clean fuels and electricity poses a particularly serious health risk. Although energy efficiency has many advantages, energy use is essential to human society and has numerous health benefits.

Which of the following is a nonpolar molecule?
mylen [45]

<u>Answer:</u> The correct option is A) a nitrogen molecule.

<u>Explanation:</u>

Polar covalent molecules are defined as chemical compounds in which the difference in electronegativity between the atoms is not equal to 0. These molecules are formed by heteronuclear molecules.

Heteronuclear molecules are defined as the molecules which are formed by the combination of more than one type of atom having a different nucleus.

Non-polar covalent molecules are defined as chemical compounds in which the difference in electronegativity between the atoms is equal to 0. These molecules are formed by homonuclear molecules.

Homonuclear molecules are defined as the molecules which are formed by the combination of one type of atom having the same nucleus.

From the given options:

  • A) A nitrogen molecule

It is a homonuclear molecule formed by the combination of 2 nitrogen atoms

  • B) A nitrogen monoxide molecule

It is a heteronuclear molecule formed by the combination of 1 nitrogen and 1 oxygen atoms

  • C) A linear nitrogen oxide molecule (N_2O) with nitrogen in the center

It is a heteronuclear molecule formed by the combination of 2 nitrogen and 1 oxygen atom and has some dipole moment. Thus, is considered a polar molecule

  • D) A bent nitrogen dioxide molecule (NO_2) with nitrogen in the center

It is a heteronuclear molecule formed by the combination of 1 nitrogen and 2 oxygen atoms and has some dipole moment. Thus, is considered a polar molecule

Hence, the correct option is A) a nitrogen molecule.

The celery and carrot will most likely become saltier and perhaps more shriveled because of the high concentration of salt in the water solution compared to the low concentration of salt in the solution. The raisin, however, could take two roots, one would be the same as the carrot and celery, but the other one is it would soak up water because of how salty and shriveled the raisin already is.
