Calculate the fall in temperature of helium initially at 15^@C , when it is suddenly expanded to 8 times its volume. (y= 5/3)

Calculate the fall in temperature of helium initially at 15^(@)C , when it is suddenly expanded to 8 times its original volume (gamma=5//3) .

The fall in temperature of helium gas initially at 20^(@) when it is suddenly expanded to 8 times its original volume is (gamma=(5)/(3))

The fall in temperature of helium gas initially at 20^(@) when it is suddenly expanded to 8 times its original volume is (gamma=(5)/(3))

Calculate the number of moles of helium in 6.46 gm of helium (at wt. of helium =4)

Radiation coming from transition n = 2 to n = 1 of hydrogen atoms falls on helium in n = 1 and n= 2 state what are the possible transition of helium ions as they absorb energy from the radiation?
