What is the density of a object whose dimensions are 5.54
Tcecarenko [31]

The object with dimensions 5.54\ cm \times 10.6\ cm \times 199\ cm and with mass 250.6 g will have a density equal to 0.02144\ g/cm^3.

<h3><u>Explanation:</u></h3>

<u>Given:</u>

Dimensions of the object = 5.54\ cm \times 10.6\ cm \times 199\ cm

length = l = 5.54 cm

width = w = 10.6 cm

height = h = 199 cm

Mass of the object = m = 250.6 g

<u>Formula:</u>

The relation between density, mass and volume of any object is given by:

Density = \frac{ Mass }{Volume}

Since volume of an object with length (l), width (w) and height (h) [assuming a rectangular object] can be defined as,

V = l \times w \times h =5.54 \times 10.6 \times 199

Volume = V = 11686.076\ cm^3

Density = Mass / Volume = \frac{250}{11686.076}

Density = 0.02144 g/cm^3

Density of the object is 0.02144 g/cm^3

What is the outdoor temperature where you are right now?.
rusak2 [61]

The outdoor temperature, also known as the ambient temperature, is a measure of the amount of heat in the environment and this depends on the kind of environment.

<h3>Temperature</h3>

The outdoor temperature around here is about 33 ^oC.

The temperature in the tropical area, where this area belongs, varies between 27 to 35 ^oC with an annual average of about 28 ^oC.

In order words, tropical regions are generally warm, unlike temperate regions.

Tropical regions also have two distinct seasons, the rainy and the dry seasons. This is unlike temperate regions that have summer, spring, winter, and autumn.

Which is a property of ionic compounds? soft and brittle low boiling point able to conduct electricity low melting point?
leonid [27]
Ionic compound generally has high melting point due to the strong ionic bond. It is also hard but brittle because repulsion between oppositely charged ions will occur if force is applied. It is soluble in water but insoluble in non-aqueous solvent. It can only conduct electricity when molten or in aqueous solution and undergo chemical decomposition upon conducting electricity.

Why is fluorine a gas?​
mart [117]

Answer:

In fluorine, the electrons are tightly held to the nuclei. The electrons have little chance to wander to one side of the molecule, so the London dispersion forces are relatively weak. At a low enough temperature the molecules will all be solids. At a high enough temperature they will all be gases.

PLEASE ANSWER!
Marianna [84]

Answer:

0.7atm

Explanation:

Given parameters:

Initial temperature = 25.2°C  in Kelvin;  25.2 + 273  = 298.2K

Initial pressure  = 0.6atm

Final temperature  = 72.4°C in kelvin  = 72.4 + 273  = 345.4K

Unknown:

Final pressure  = ?

Solution:

Since we are dealing with pressure temperature relationships under a fixed volume, we use a simplification of the combined gas law to solve this problem.

 At fixed volume;

             \frac{P_{1} }{T_{1} }   = \frac{P_{2} }{_T{2} }

  where P and T are temperature values

              1 and 2 are the initial and final states

Input the parameters and solve for P₂

            \frac{0.6}{298.2}   = \frac{P_{2} }{345.4}  

            P₂   = 0.7atm
