Similarities and differences between solids liquids and gases

Chemistry
1 answer:
Masteriza [31]4 years ago
8 0

Answer:

Detail is given below.

Explanation:

Similarities:

All are the forms of matter.

Solid, liquid and gases are made up of ions, atoms and molecules.

They have shape and volume.

Molecules in Liquid and solid are closer to each others.

Liquid and gases can flow very easily.

Liquid and solid both can not compressed very easily.

Differences:

Molecule of gases randomly move everywhere and occupy all available space but liquid and solid's molecules are not move as much easier as molecules of gases can.

The density of gases are very low as compared to the liquid and solid.

Gas molecules are at long distance from each other while in liquid and solid they are closer to each other.

The very weak inter molecular forces are present between gas molecules as compared to the liquid and solids.

Solids have definite volume and shape but liquid and gases acquire the shape of container.

In solids molecules are tightly pack and very close to each other while in liquid molecules are not tightly pack like in case of solid.

The densities of solids are also very high as compared to the liquid and gas.

There are very strong inter molecular forces are present between solid molecules.

Answer:

The number, such as 98.7 FM, of a radio station represents:

  • <u>the frequency in which is transmitted the radio signal</u>.

Explanation:

<em>The radio FM is the modulated frequency, which means that all the information is sent by just a signal, with different frequencies which difference them</em>, <u>the radio FM use the frequencies from 88 MHz until 108 Mhz (MHz is a measuring unit for the frequency), with a minimal space among them of 0.2 MHz</u>, this last means that you could find a signal in 88.0 MHz, and the next should be 88.2 MHz, next 88.4 MHz and so (at least, regularly the space between two frequencies is more than 0.2 MHz).

The normal freezing point of a certain liquid Xis-7.30°C but when l02. g of iron(III) chloride (FeCl3) are dissolved in 650. g o
IRISSAK [1]

Answer:

2.7 °C.kg/mol

Explanation:

Step 1: Calculate the freezing point depression (ΔT)

The normal freezing point of a certain liquid X is-7.30°C and the solution freezes at -9.9°C instead. The freezing point depression is:

ΔT = -7.30 °C - (-9.9 °C) = 2.6 °C

Step 2: Calculate the molality of the solution (b)

We will use the following expression.

b = mass of solute / molar mass of solute × kilograms of solvent

b = 102. g / (162.2 g/mol) × 0.650 kg = 0.967 mol/kg

Step 3: Calculate the molal freezing point depression constant Kf of X

Freezing point depression is a colligative property. It can be calculated using the following expression.

ΔT = Kf × b

Kf = ΔT / b

Kf = 2.6 °C / (0.967 mol/kg) = 2.7 °C.kg/mol
