I just need help to solve a problem:
Show that (∂E/∂V)β, N + β(∂p/∂β)N, V = - p
PS: There is a bar over E and over p (this in both sides) - meaning that is an average.

1. An unbreakable meteorological balloon is released from the ground.Ground level pressure is 98.5 KPa and the temperature is 18.0 Celsius. The balloon contains 74.0 liters of Hydrogen gas. As the balloon soars up, the pressure drops to 27.0 KPa. What is the new volume of the balloon, assuming no temperature change?
2. Re-read question 1, but considering in the real world when you go up in altitude the temperature does change. what is the actual volume of the meteorological balloon if the temp also drops 79.0 celsius from its original temperature?

Do conduction phenomenon occur in air ?
If not what is responsible for the experiment of action of point in which air molecules get charged and are repelled as a result strong electric wind develops which blow a candle flame kept aside in experiment ?
