A sample of `2kg` of helium (assumed ideal) is taken through the process `ABC` and another sample of `2kg` of the same gas is taken through the process `ADC`. Then the temperature of the states `A` and `B` are (given `R = 8.3J mol^(-1)K^(-1))`

A

`T_(A) = 120.5K, T_(B) =120.5K`

B

`T_(A) = 241K, T_(B) =241K`

C

`T_(A) = 120.5K, T_(B) = 241 K`

D

`T_(A) = 241K, T_(B) = 482K`
