Gas molecules have more freedom in motion—and gases can be thought of as more “disordered”—than molecules of a solid, which are rigidly held in place. When it comes to phases, the entropy increases as you go from a solid to liquid to gas (the gaseous state having the greatest entropy and the solid state having the least).

So, as a sample of solid iodine sublimes to form gaseous iodine, the entropy of the sample increases.

Convert the boiling temperature at gold, 2966 degree centigrate , into degrees fahrenheit and kelvin.

nexus9112 [7]

Answer:

Boiling point of gold is 1630 $^{0}\textrm{F}$ or 3239.15 K

Explanation:

We know, $T(^{0}\textrm{F})=1.8T(^{0}\textrm{C})+32$

Here $T(^{0}\textrm{C})$ and $T(^{0}\textrm{F})$ are temperature in degree centigrate and temperature in degree farhenite respectively.

So, $2966^{0}\textrm{C}=\frac{2966-32}{1.8}^{0}\textrm{F}$

= 1630 $^{0}\textrm{F}$

We know, $1^{0}\textrm{C}=273.15 K$

So, 2966 $^{0}\textrm{C}$ = (2966+273.15) K = 3239.15 K

Identify each type of bond:

zloy xaker [14]

Answer:

The type of bond between the Oxygen atom and the hydrogen is Covalent

this is because the 2 electrons are being shared by both hydrogen and oxygen

The type of bond this molecule makes as a whole is called a Hydrogen Bond

A hydrogen bond is formed because of the partial +ve and -ve charge in a molecule

The cause of the partial +ve and -ve charge is the comparatively high electronegativity of oxygen which makes the electron get attracted towards the oxygen atom while the hydrogens try to maintain the maximum distance from the lone pairs due to repulsion
