Answer:

<h2><u>ADVANTAGES OF THE PERIODIC TABLE:</u></h2>

It is easier to remember the properties of an element if its position in the periodic table is known.
The periodic table has made the study of chemistry systematic and easy.
The type of compounds formed by an element can be predicted by knowing it position in the periodic table.

A sealed container at 25oC contains a gas at a pressure of 104 kPa. What is the pressure of the gas when it is heated to 225oC?

seropon [69]

Answer:

174 kPa

Explanation:

Given that,

Initial temperature, T₁ = 25° C = 25+273 = 298 K

Final temperature, T₂ = 225°C = 225 + 273 = 498 K

Initial pressure, P₁ = 104 kPa

We need to find the new pressure. The relation between the temperature and pressure is given by :

$\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}$

So,

$P_2=\dfrac{P_1T_2}{T_1}\\\\P_2=\dfrac{104\times 498}{298}\\\\P_2=173.79\ kPa$

P₂ = 174 kPa

So, the new pressure is 174 kPa.

In the phase diagram below, point B describes the critical point.<br><br><br><br> TRUE<br><br> FALSE

White raven [17]

The critical point is said to be the end point of a phase diagram. The most known example is the liquid-vapor critical point, the point in a PT curve that signifies that at this point both vapor and liquid coexist. The critical point is characterized by a critical pressure and a critical temperature.
