Which is true for a substance that absorbs energy?

just olya [345]

Answer:

A. The energy increases the molecular motion and the kinetic energy of the substance.

Explanation:

When a substance absorbs energy, the molecules will move faster because there will be more vibrations and collisions.

As a result of more molecular motion, the kinetic energy will increase because there is more movement.

A client has the following arterial blood gas (ABG) values: pH, 7.12; partial pressure of arterial carbon dioxide (PaCO2), 40 mm

USPshnik [31]

Answer:

Most likely a mixed acidosis

Explanation:

Mixed acidosis is when you have metabolic acidosis and respiratory acidosis, the concentration of bicarbonate, that must be between 19.1 and 24.7, is 15, so it is below the lesser value. The partial pressure of carbon dioxide should be between 28.3 and 38.7, and client's partial pressure of carbon dioxide is slightly above the upper limit. Finally, pH sould be between 7.39 and 7.47, and client's pH is below the lesser limit. This all means that the blood is too acid.

Answer:

All matter is made up of tiny particles called atoms. Atoms are made up of three subatomic particles known as proton, neutron and electron. Protons and neutrons are located in the nucleus.

The nucleus is dense and takes up very little space within the atom. All protons have a positive charge and have a mass of about 1 amu. All neutrons have no charge or are neutral and have a mass of about 1 amu.

Electrons are located in the area known as electron cloud. Electrons orbit around the nucleus and have a negative charge

In the first law of thermodynamics, △E = Q-w, what does △E stand for?

Damm [24]

Answer: The correct answer is Option B.

Explanation:

First law of thermodynamics states that the energy can neither be destroyed not be formed but it can only be transformed from one form to another.

Here, the internal energy of the system is being transformed to the heat energy and the work done by the system. The equation used to represent first law of thermodynamic is:

$\Delta E=Q-w$

where,

$\Delta E$ represents the internal energy of the system.

Q = heat released or absorbed by the system.

w = work done by or on the system.

Hence, the correct answer is Option B.
