### Temperature

If the temperature is not given in a problem do we assume it is at room temperature and use that for T?

### Re: Temperature

If not indicated you can usually assume the system is under standard conditions (25* C).

Yes! It would be in standard aka 25° :)

### Re: Temperature

Yes, we could assume that temperature would be at standard state, which is 25 degrees C, or 298 K.

### Re: Temperature

Yes, if they don't give us temperature, assume that it is at 25 degrees celsius.

Yeo, we assume the reaction is at standard temperature and pressure.

Usually, yes, if not try to use the ideal gas equation to solve for it!

### Re: Temperature

Yes, I believe we are meant to assume that the temperature is 25 degrees C if it is not explicitly stated in the problem.

### Re: Temperature

Also consider that if the temperature is not given, it's possible that the problem doesn't actually require PV=nRT and that you should try a different approach.

I'm pretty sure we are supposed to assume that it is standard and is at 25 degrees C.

### Re: Temperature

Yes, when the temperature is not given we assume it is at 25 celsius. Just keep in mind that the problem you are solving might require temperature in Kelvin so you might need to convert it.

### Re: Temperature

If it isn't given in a problem, you usually assume it's 298 K (or 25°C). I used to wonder this too but that is how it is in a lot of the Sapling textbook questions. If there is any ambiguity during an exam and you just want to be safe, I'm sure your TA will clarify it anyway.

### Re: Temperature

Yep! Usually the question will say "standard room temperature" if they do not specify a temperature, meaning that it is at 25˚C or 298K.

### Re: Temperature

Yes if not given assume room temperature at 25*C, and I think Professor Lavelle mentions that every lecture when temp is not specified.

Hope this helps.
