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).

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

Re: Temperature
Yes, I believe that if it isn't specified, we assume it's standard temperature and pressure.

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.
Re: Temperature
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
Yep! I believe Lavelle mentioned that if it doesn't state it, we can assume it's at 25 degrees C.

Re: Temperature
Yup, you should assume the temperature is at standard conditions of 25 degrees C, or 298 K.

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, you should assume standard conditions. which for temperature means 25 degrees celcius/298 K

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.

Re: Temperature
You should assume it's 25ºC or 298K just make sure to look at what the problem is asking

Re: Temperature
If the temperature is not given in a problem, typically just assume 25 degrees Celsius or 298.15 degrees Kelvin.

Re: Temperature
I'm fairly certain we just assume 25 degrees Celsius, but I also think that if given a K constant, that is the one you would use in solving the problem, since we haven't learned the arrhenius equation.

Re: Temperature
If temperature is not given in a problem, assume the standard condition for temperature, which is 25°C. Make sure to keep in mind which temperature unit is required to solve the problem as you may have to convert the temperature from Celsius to Kelvin.

Re: Temperature
Yes! I think the correct assumption, if T is not stated, is 25 C, which is room temperature!

Re: Temperature
Yes if temperature is not specified in a given problem, then always assume that the reaction is taking plac eunder standard condtions hence the temperature would be 25 C.

Re: Temperature
I do believe that in this case, we would assume a temperature of 25 degrees celsius, or 298 K, depending on which SI units are asked for.

Re: Temperature
If the problem doesn't specify the temperature value, you would assume the reaction is in standard condition where the temperature is 25 degrees C or 298K.
Re: Temperature
Assume it is 298 Kelvins (25 Celsius) which is STP or standard temperature and pressure

Re: Temperature
Im pretty sure if temperature is not given to us we would use 25 degrees celsius or 288 kelvins based on the equation.
Hope this helps.

Re: Temperature
Yes, unless the problem specifies the temperature in the problem, the rule of thumb would be to assume standard conditions. As such temperature would be taken to be 25 degrees Celsius.

Re: Temperature
If temperature is not given in a problem then you can likely assume standard conditions unless otherwise stated.
Standard conditions would be 25 degrees C or 298 K.

Re: Temperature
There is usually some sort of indication of temperature. If it is not explicitly stated then the problem might not need temperature OR it says that the problem says that it is looking for an answer in standard conditions in some sort of variation.

Re: Temperature
Yes, normally it's assumed that the reaction occurs in standard conditions (298K = 0C).
Re: Temperature
Yes, if it doesn't specify we can assume that the reaction is carried out under standard conditions (25 degrees C or 298 K).

Re: Temperature
For the purposes of this class, yes, you would assume 25 deg C. Temperature should be given for problems that need you to know temperature but if the information is omitted then it's probably not a special case.
