The appropriate answer is d. recording and studying seismic waves. Seismic waves behave differently as the enter the different layers of the Earth. Scientists used seismic or earthquake waves to determine the different layers of the Earth. The behaviour of the waves as they move through the layers helped scientists identify the boundaries and the state of each layer; solid or liquid.

The Nernst equation at 20oC is:
saw5 [17]

Answer:

a. -58 millivolts

Explanation:

The given Nernst equation is:

E_{ion} = 58 millivolts /z \Big[ log_{10} \Big( \dfrac{[ion]_{out}}{[ion]_{in}}\Big) \Big]}

The equilibrium potential given by the Nernst equation can be determined by using the formula:

E_{Cl^-} = \dfrac{2.303*R*T}{ZF} \times log \dfrac{[Cl^-]_{out}} {[Cl^-]_{in}}

where:

gas constant(R) = 8.314 J/K/mol

Temperature (T) = (20+273)K

= 298K

Faraday constant F = 96485 C/mol

Number of electron on Cl = -1

E_{Cl^-} = \dfrac{2.303*8.314*298} {(-1)*(96845)} \times log \dfrac{100} {10}

E_{Cl^-} = - 0.05814  \ volts

\mathsf{E_{Cl^-} = - 0.05814  \times 1000 \  milli volts}

\mathsf{E_{Cl^-} \simeq - 58\   milli volts}

Thermal energy added to a substance that is not changing state causes the substance’s temperature to
tatyana61 [14]

Answer:

increase

Explanation:

Conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction. Conductors include metal, steel, aluminum, copper, frying pan, pot, spoon etc.

In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.

Hence, thermal energy added to a substance that is not changing state causes the substance’s temperature to increase because it would absorb energy in the form of heat.
