Charles law gives the relationship between volume of gas and temperature.
It states that for a fixed amount of gas at constant pressure, volume of gas is directly proportional to the temperature.
where V - volume and T - temperature and k - constant
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
T1 - temperature in Kelvin , -206.6 °C + 273.15 = 66.55 K
T2 - 175.9 °C + 273.15 = 449.05 K
substituting the values in the equation
V = 782 mL
the new volume is 782 mL
Answer:
The energy required to remove the the electrons from gaseous atom is called ionization energy.
Explanation:
Ionization energy:
The amount of energy required to remove the electron from gaseous atom is called ionization energy.
Trend of ionization energy in periodic table:
Along period:
The atomic size tend to decrease in same period of periodic table with increase of atomic number because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required.
Along group:
Atomic size increases with increase of atomic number from top to bottom. The nuclear attraction on valance shell became weaker and thus it becomes easy to remove an electron from valance shell and this can be done with less amount of energy. That's why ionization energy decreases from top to bottom.

The type of bonding and the numbers of covalent bonds an atom can form with other atoms are determined by the unpaired electrons present in the valence shell. The electrons are called the valence electrons. These are the electrons that can participate in chemical bonding.
