Agas sample has a volume of 178 ml of 0.00 degrees c. the temperature is raised (at constant pressure) until the volume reaches 211 ml. what is the temperature of the gas sample in degrees c at this volume?

The temperature of the gas was 50.46°C.

Explanation:

To calculate the final volume when temperature increases, we use Charles' Law which states that the volume is directly proportional to the temperature of the gas if number of moles and pressure remains constant.

Mathematically,

where,

= Initial volume and temperature

= Final volume and temperature

We are given:

Putting values in above equation, we get:  

      (Conversion factor: T(K) = T(°C) + 273.15)

Hence, the temperature of the gas is 50.46°C

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.
