Answer:
Answer is very easy
Explanation:
23°C + 273.15 = 296.15K
296.15 kelvin
Answer:
Room temperature varies depending on what type of room it is, who uses it, and where in the world it is. In Norway, room temperature is between 20 and 22 degrees Celsius, discounting bedrooms, which are often down to 16–18 degrees.
Engineers like myself have certain formulas to use to determine what should be the temperature for a given room. The amount of clothing typically used in the room, and what sorts of activities usually determines this. In a classroom for example, people usually sit still with medium amount of clothes, while a sports gym is little clothing with high activity. Much research is being done on places like hockey rigs, where the athletes have much clothing and high activity, while audience usually has little activity and preferably medium clothing. Them being in the same room is a challenge, comfortwise.
In addition to this, people's own preferences come into consideration, and usually there's a bell curve depicting dissatisfaction among users, and the goal is that the fewest amount of people should be dissatisfied. The peak of the bell curve amounts to around 5% of the population being dissatisfied. Can't please everyone. This curve is usually based on surveys done in the past for similar buildings.
Another important factor is that the temperature difference between the head area and the feet area should be no more than 2 degrees, or the difference will be noticeable, leading to discomfort. If a slight alteration of temperature could ensure that, then it's usually worth it.
Tl;dr: Room temperature varies, but the temperatures are what they are for a reason.
Edit: Outer skin temperature is also a deciding factor for comfort. If you give away heat or receive heat through the skin, then the temperature is not ideal.
