Answer:

Warm or hot air particles have more energy than that of cool air. As a result they move faster than cool air particles. Since sound propogation involves movement or vibration of particles, sound travels faster in warm air

Hope this helps!

Heat allows particles to gain more energy, including those in the air. This is why heating makes chemical reactions happen quicker. As the air particles have more energy, they will move faster and bump into each other faster, allowing for the sound to travel quicker

Mercury is a liquid metal having a density of 13.6 gml what is the volume of 1.00 lb of mercury metal

tresset_1 [31]

The volume of 1.00 lb of mercury metal : 33.352 ml

<h3>Further explanation </h3>

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

Density formula:

$\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}$

ρ = density

m = mass

v = volume

Density of metal(mercury) = 13.6 g/ml

mass of mercury : 1 lb = 453,592 g

So the volume :

$\tt V=\dfrac{453,592~g}{13.6~g/ml}\\\\V=33.352~ml$

Nurse Antonio measured out 7 grams of sodium chloride (NaCI). Using dimensional analysis, calculate how many moles of NaCI he we

Neporo4naja [7]

Answer:

0.119 moles

Explanation:

Given that,

Mass measured by Nurse Antonio is 7 grams of NaCl

To find,

The no of moles of NaCl

Solution,

The number of moles is given by

$n=\dfrac{m}{M}$

m is given mass

M is molar mass

For NaCl, molar mass is 23+35.5 = 58.5 grams

So,

$n=\dfrac{7}{58.5}\\\\n=0.119\ \text{moles}$

Therefore, there are 0.119 moles of NaCl.

Roman mixes 12 liters of 8% acid solution with a 20% acid solution, which results in a 16% acid solution. Find the number of lit

inysia [295]

Let the 8% solution be A, the 20% solution be B and the final solution be C.

C = A + B
C = 12 + B

0.16C = 0.08(12) + 0.2(B)
0.16(12 + B) = 0.96 + 0.2B
0.96 = 0.04B
B = 24 Liters

C = 12 + 24
C = 36 Liters
