Answer:

Explanation:

Convection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy). When the cause of the convection is unspecified, convection due to the effects of thermal expansion and buoyancy can be assumed. Convection may also take place in soft solids or mixtures where particles can flow.

In an airplane, a gas sample occurs at a volume of 1.5 L at 760.0 torr. Suppose, while flying, the airplane loses pressure and t

jekas [21]

Answer:

100 torr

Explanation:

First find the formula you need to use, this will be...

P2 = V1 x P1 / V2

Next, fill in the numbers, this will be...

P2 = ? (we are trying to find this)

P1 = 760 torr

V1 = 1.5 L

V2 = 11.4 L

Next, turn into new formula (just rearrange)

P2 = 1.5 L x 760 torr / 11.4 L

Next, do the math. This should get you...

<u>100 torr</u> as your answer

- Let me know if you need more help understanding. I would be glad to further explain or do more problems.
