Waves move fastest in low-temperature gases. low-temperature solids. high-temperature gases. high-temperature solids.

Answers

Answer 1

Answer:

Answer: Option (d) is the correct answer.

Explanation:

At high temperature, there will be more collision between the molecules as a result more energy will generate. Thus, a wave can move quickly.

In case of solids, the particles are held more closely with each other. Therefore, when temperature is high then solid particles being closer can pass on the energy more quickly as compared to gases.

Thus, we can conclude that waves move fastest in high-temperature solids.

Answer 2

Answer:

Final answer:

In Physics, waves move fastest in high-temperature solids due to the close proximity of particles which facilitates faster wave transmission and the increased kinetic energy at high temperatures.

Explanation:

In the study of Physics, the speed of sound waves varies depending on the properties of the medium through which they are traveling. Solids have tightly packed particles which facilitate faster wave transmission. Conversely, gases have loosely packed particles which slow down wave travel. Temperature, while affecting speed at some level, doesn't have as significant an influence as the state of matter itself.

Therefore, among the options you provided: low-temperature gases, low-temperature solids, high-temperature gases, and high-temperature solids, waves move fastest in high-temperature solids.

This is due to the increased kinetic energy of the particles in a high-temperature solid as compared to a low-temperature solid; and the closer proximity of particles in a solid as compared to a gas.

What is the total number of moles of solute in 250 milliliters of a 1.0 M solution of NaCl

Answers

First, the Molarity equation is M = mol/L. However, the problem is looking for the TOTAL NUMBER OF MOLES in which will have you to reposition the said equation: mol = M/L. Observe that you need L not mL, so you need to convert 250 mL to L that will results to .25 L. Then, substitute the value of the units to the formula and you should be able to get 4 moles.

The two gases that can cause changes in a mud's pH are carbon dioxide (CO2) and hydrogen sulfide (H2S). These gases can dissolve in water and form acids, leading to a decrease in pH.

WILL MARK BRAINIESTIf the molecules of two different substances have a similar size but the molecules of one substance are polar while the molecules of the other substance are nonpolar, what is most likely true about the substances?
A The polar substance has a lower boiling point than the nonpolar substance.
BThe nonpolar substance has a lower boiling point than the polar substance.
C Both substances have similar volatilities.
DBoth substances have similar solubilities.

Answers

Answer:

The correct option is B. The nonpolar substance has a lower boiling point than the polar substance.

Explanation:

Substances with hydrogen bonding, an intermolecular force, will have much higher boiling points than those that have ordinary dipole-dipole intramolecular forces. Non-polar molecules have lower boiling points, because they are held together by the weak van der Waals forces.

Note

However, if size of non polar increases, then its boiling point increases due to increases in van der walls forces with large size.

The correct answer is letter B: the non polar substance has a lower boiling point than the polar substance.
