A 4.700 L sample of gas is cooled from 71.0 °C to a temperature at which its volume is 3.300 L. What is this new temperature? As
Dafna11 [192]

initial condition : Vi = 4.700 L , Ti = 71.0ºC +273 => 344 K

final condition : Vf = 3.300 L , Tf = ?

Pressure is constant:

According to charle's law , volume is directly proportional to temperature at constant pressure !

Hence  Vi / Ti  = Vf / Tf

4.700 L / 344 K = 3.300 L / Tf

Tf =  3.300 L * 344 K / 4.700 L

Tf = 1135200 / 4.700

Tf = 241.53 K

Tf = 241.53 - 273

Tf = -31.47ºC

Describe how plants might be affected if the inter molecular forces in water decreased? i need asap!
vovangra [49]

Answer:

Water has polar O-H bonds. The negative O atoms attract the positive H atoms in nearby molecules, leading to the unusually strong type of dipole-dipole force called a hydrogen bond. Since water has hydrogen bonds, it also has dipole-induced dipole and London dispersion forces.

Hope it helped!!

The diagram shows monochromatic light passing through
Maru [420]

Destructive interference in which waves cancel each  other out is depicted in region X,Y and Z.

<u>Explanation:</u>

Interface is the particle property of light waves. When incident light beam is made to pass through holes, the waves will combine either constructively or destructively. Constructive interference means the waves having same phase will get added so they will increase in amplitude. While destructive interference means the waves combining have different phases like crests and troughs. So they undergo decrease or complete vanishing of amplitude.

When waves combine in constructive interference, they form bright white light and when they combine in destructive interference, they form dark black light. So the regions X, Y and Z are shown as dark black colors in the diagram, so these regions represent destructive interference in which waves cancel each  other out.
