A rigid cylinder with a movable piston contains a sample of gas. At 300. K, this sample has a pressure of 240. kilopascals and a volume of 70.0 millilitres. What is the volume of this sample when the temperature is changed to 150. K and the pressure is changed to 160. kilopascals? Based on the reading above, what is the final temperature?
1) 300 K
2) 160 kPa
3) 70 mL
4) 150 K

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )

answer carbon and three oxygen atoms;

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
