One mole of an ideal gas at 25^(@)C expands in volume from 1.0 L to 4.0 L at constant temperature. What work (in J) is done if the gas expands against vacuum (P_("external") = 0)?

One mole of an ideal gas at 25^(@)C expands in volume from 1.0 L to 4.

1.	One mole of an ideal gas at 25^(@)C expands in volume from 1.0 L to 4.0 L at constant temperature. What work (in J) is done if the gas expands against vacuum (P_("external") = 0)?
Answer» `-4.0 XX 10^(2)` `-3.0 xx 10^(2)` `-1.0 xx 10^(2)` Zero Solution :`w=-intPdV=0`
