Help! Will mark brainliest! Explain why a mechanical wave does not exist in a vacuum.

1 answer:

7 0

Light waves are a wave in the electromagnetic field, this field may exist in a vacuum. Sound needs either solid, liquid, or gas to propagate and therefore it is called a mechanical wave. Sound is a form of energy which is transferred by vibrating air molecules if motions of propagation is air.

A sample of methane gas has a volume of 10 l at a pressure of 1.5 atm and a temperature of 20 °c. what volume does the gas occup

a_sh-v [17]

We can use combined gas laws to solve for the volume of the gas
$\frac{PV}{T}$
where P - pressure, V - volume , T - temperature and k - constant
$\frac{P1V1}{T1} = \frac{P2V2}{T2}$
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
T1 - temperature in Kelvin - 20 °C + 273 = 293 K
T2 - 40 °C + 273 = 313 K
substituting the values
$\frac{1.5 atm*10L}{293 K} = \frac{0.9 atm*V}{313K}$
V = 17.8 L
volume of the gas is 17.8 L

Is the osmosis egg challenge a chemical reaction?

Vikki [24]

Answer:

Answer is C because in exothermic reactions, energy releases.

in Cellular respiration,

ATP+H20 (water) = ADP+ Pi + Energy

So celullar respiration is exothermic and releases energy

A 5.00-l tank contains helium gas at 1.50 atm. what is the pressure of the gas in torr if volume is doubled

vazorg [7]

570 torr. The ideal gas law is PV = nRT where P = pressure V = volume n = number of moles of gas particles R = Ideal gas constant T = absolute temperature Since the value n, R, and T remain constant for this problem, that indicates that if the volume is doubled, the pressure will be halved. So the new pressure will be 1.50 atm / 2 = 0.750 atm. Now we just need to convert that from atm to torr. 1 atm is equal to 760 torr, so 0.750 atm * 760 torr/atm = 570 torr.
