How much time will it take a car travelling at 88 km/hr (55mi/hr)to travel 500km?
dybincka [34]
The time it will take for a car travelling 88 km/hr (55mi/hr) to travel 500km would be 3.5 hours.

How? Add 88 + 58.

That'll equal 143, then divide 500 ÷ 143 = 3.5

So, 3.5 is the time that the car will take travelling 88 km/hr trying to reach the destination of 500km.

Which Of the following, the best explanation for the fact that most gases are easily compressed is that the molecules in a gas a
Otrada [13]

Answer: A. are relatively far apart

Explanation:

Compressbility is the ability of compound to reduce in size when pressure is applied.

Gaseous state is a state in which the particles are loosely arranged and have a lot of space between them. Thus molecules can be easily compressed.

They have highest kinetic energy. This state has indefinite volume as well as shape.  The molecules in the gaseous state move faster with an increase in temperature as the kinetic energy increases with increase in temperature.

Thus most gases are easily compressed is that the molecules in a gas are in constant motion are relatively far apart.

A gaseous compound has a mass of 8.00 g at 2.81 atm and 300. K in a 1.00 L container.
Maurinko [17]

Answer:

The question asks for moles, which can be obtained from P-V-T data using the ideal gas

equation: n =

RT

PV .

Now use the rearranged gas law to determine the number of moles in the sample:

!

n = PV

RT = (6.47 x 105 Pa)(5.65 x 10-4m3

)

(8.314 J

mol K )(21.7 + 273.15 K) = 0.149 mol.

All conditions except the pressure and volume are fixed, so P1V1 = P2V2 can be used: 3.62 L

101kPa

(647 kPa)(0.565 L)

2

1 1

2 = =

P

PV V
