The families, or groups, have similar properties, for example, the first group 1 are made of extremely reactive metals. They will also have similar boiling, melting, and conductivity. With valence electrons all in the same orbital (alkaline metals all have valence electrons in the s orbital)<span />
Answer:
Pressure=3.91atm
Explanation:
As given in the question that gas is ideal so
we can use Ideal gas equation

volume of gas is not given directly but volume of container is given and we know gas takes the volume in which they are kept.
therefore mole remains contant
P1=2.5 atm
V1=2L
T1=320K
P1=?
V1=1L
T1=250K
..............(1)
................(2)
eqn2/eqn1

Pressure=3.91atm
