A 2 L balloon filled with gas is warmed from 280 K to 700 K. What is the volume of the gas after it is heated?

irakobra [83]

Answer:

New volume, v2 = 0.8L

Explanation:

<u>Given the following data;</u>

Original Volume = 2L

Original Temperature = 280K

New Temperature = 700K

To find new volume V2, we would use Charles' law.

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles is given by;

$VT = K$

$\frac{V1}{T1} = \frac{V2}{T2}$

Making V2 as the subject formula, we have;

$V_{2}= \frac{V1}{T1} * T_{2}$

$V_{2}= \frac{2}{700} * 280$

$V_{2}= 0.0029 * 280$

V2 = 0.8L

Therefore, the volume of the gas after it is heated is 0.8L.

Law Incorporation [45]

Answer:

Third displacement = 2.81 m which is 61.70° north of east.

Explanation:

Let east represents positive x- axis and north represent positive y - axis. Horizontal component is i and vertical component is j.

She sails 2 km east, displacement = 2 i

Then 3.50 km southeast, means 3.5 km 315⁰ to + ve X axis

Displacement = 3.5 cos 315 i + 3.5 sin 315 = 2.47 i - 2.47 j

Let third displacement be x i + y j

We have final displacement = 5.80 km east = 5.80 i

From summation we have total displacement = 2 i + 2.47 i - 2.47 j + x i + y j

= (4.47+x) i + (y - 2.47) j

Comparing both , we have 4.47+x = 5.80

x = 1.33

y-2.47=0

y = 2.47 j

So third displacement = 1.33 i + 2.47 j

Magnitude of third displacement = $\sqrt{1.33^2+2.47^2} =2.81m$

θ = tan⁻¹(2.47/1.33) = 61.70°

So third displacement = 2.81 m which is 61.70° north of east.
