Answer: Option (a) is the correct option.
Explanation:
In order to travel, sound does need a medium. The more closer the particles of a medium, the better sound can travel through it. Therefore, in solids sound travels very quickly because in solids particles are closer to each other. As a result, they can easily transmit the energy from one particle to another.
Thus, it becomes easier for sound to travel through it. On the other hand, in solids sound can travel in both longitudinal and transverse waves.
Hence, out of the given options, sound travels in transverse waves requires a medium to travel through is the correct option.
When ammonium chloride NH4Cl is added to water and stirred, it dissolves spontaneously (this is the basis for ΔG) for and the resulting solution feels cold (endothermic, the basis for ΔH). Without doing any calculations, we can easily deduce the signs of ΔG, ΔH, and ΔS for this process based on the observations.
ΔG < 0 (it is spontaneous)
ΔH < 0 (because the process is endothermic - it absorbs energy)
ΔS > 0 (entropy increases because of the dissolution of NH4Cl in water
Answer:
4.2 x 10⁴ mL
Explanation:
Data Given:
Density (d) of air = 1.19 x 10⁻³g/mL
Mass of the air (m) = 50 g
Volume of the air (V) = ?
Solution:
Formula will be used
d = m/V
As we have to find volume so rearrange the above equation
V = m/d . . . . . . . . . . . (1)
Put values in above equation 1
V = 50 g / 1.19 x 10⁻³g/mL
V = 4.2 x 10⁴ mL
So,
volume of dry air = 4.2 x 10⁴ mL
