A ballon is filled with 1.22 L of gas at 286 K is heated until the volume is 2.86 L while the pressure remains constant. What is the temperature of the gas in kelvin?

670.45 K

Explanation:

Given that,

Initial volume, V₁ = 1.22 L

Initial temperature, T₁ = 286 K

Final volume, V₂ =  2.86 L

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

So, the new temperature of the gas is equal to 670.45 K.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

have a great day because if you dont you and i will be sad
