What are standard conditions?
For example, in the equation #\Delta G^{\circ} = \Delta H^{\circ} - T\Delta S^{\circ}# ,
#\Delta G^{\circ}# seems to be temperature dependent, so does that mean #\Delta G^{\circ}# only applies at a specific pressure?
For example, in the equation

See Below.
Explanation:
Examples of standard conditions are Standard Temperature, Standard Pressure, or STP (Standard Temperature and Pressure).
At STP,
Temperature = 273.15K,
Pressure = 1 atm (before 1982)
Pressure = 1 bar (after 1982)
Also, at STP,
1 mol of IDEAL gas = 22.414 L at 1 atm
1 mol of IDEAL gas = 22.711 L at 1 bar
This is not to be confused with thermodynamic standard conditions, which is what you are looking for. It is similar, but
Temperature = 298.15K,
Pressure = 1 atm (before 1982)
Pressure = 1 bar (after 1982)
