Why 25 Degrees Celsius?

Postby JacksonWissing2G » Sun Jan 16, 2022 6:07 pm

Is there a specific reason that we assume that the temperature is 25 degrees when doing calculations and not another temperature, or is 25 degrees just an arbitrary number to choose when assuming temperature?

In chemistry, 25 degrees is the uniform ambient or room temperature, just to keep consistency with calculations.

Hi! I believe 25 C is the standard room temperature used in calculations, so unless specified otherwise, we just use this value and the K value associated with it. If the temperature increases, the K also increases, so it will be a different value.

25 degrees Celsius is considered the universal room temperature, so it is often used and a change in temperature from that would then cause a change and shift in the equilibrium reaction that they are referring to.

It's simply for uniformity internationally and is used as a standard reference temperature.

https://www.quora.com/Why-are-25-degree ... emperature Reading this was helpful in finding the answer to your question! Interesting question too, I never really thought about why we assume 25 degrees celsius specifically.

It is universally considered room temperature so we use this for uniformity.

From my understanding its a set standard, kinda like how in the metric system sets 0 degrees and 100 degrees as a point of reference for temperatures at which water freezes or boils respectively.

25 degrees celsius is the standard ambient temperature formed by IUPAC. It more practical to use this as a reference temperature in experiments compared to STP conditions.

I see 25 degrees very often in problems and its basically room temperature and we have it as a reference temperature.

25 degrees is simply the easiest for scientists to reference and use when they test "standard conditions," as it is close to room temperature. So, 25 degrees doesn't have any special meaning, but rather, it is the most convenient temperature to use as a baseline for standard conditions.

25 Degrees is determined to be the temperature at which gases are observed at STP (standard temperature and pressure). It's mainly for uniformity purposes so as to make sure there remains a constant temperature throughout all these different experiments.

25 degrees is room temperature

Hello. So you can always assume that a reaction is going to occur while at 25 degrees celsius because that is the standard room temperature. The only case in which your temperature is going to be something other than 25 degrees celsius is if it is specified. Hope this helps.

25 degrees C is room temperature. For many equations and constants, they are given at temperatures 22-25 degrees C. This is just to standardize everything. If you were performing a real experiment that was under temperatures drastically different from 25 degrees C, adjustments would be made accordingly.

25 degrees celsius is considered the room temperature during chemistry experiments and is widely regarded as the universal room temperature. Always assume the reaction takes place at 25 degrees celsius unless specified otherwise.

25 degrees Celcius is agreed to be room temperature, which is why it is the standard temperature we use.

I was also a little confused about why only 25 degrees but thank you everyone who could clear this up. One question I do have that I am not fully clear on is what to do if the question states another temperature.

25 degrees Celsius tends to be the calculated room temperature that is used most often in chemistry.

25 degrees Celsius is considered the universal room temperature, meaning that all scientists across the globe have a mutual understanding that 25 is the designated value of room temperature. Therefore, if the problem does not specify, it is safe to assume.

I believe it's because it's to standardize the measurements we take for elements, but also it is the temperature in which the most stable state of pure solids and liquids are maintained.

25 degrees Celsius is room temperature and the standard used.
