Not outside, and not with things I happen to have around the house,
but it's easy to produce in a properly equipped laboratory.
285 K?
25 degrees Celsius = 298.15 kelvin[K] = [°C] + 273.15
273.16 deg K = 0.01 deg C
K = 273.15 + C K = 273.15 + -25 K = 248.15
25 kilometres = 15.5 miles
285 K?
25 C 298.15 K 20 Re
In the morning it was about 47 K, and to 8 AM. it was overcast. Then the heaven cleared, and on 2 PM. temperature reached 65 K. In the evening it overcasted again and the temperature was about 45 K.
25ºc = 298.15 k
25 degrees Celsius = 298.15 kelvin[K] = [°C] + 273.15
If we assume "room temperature" to be 25 °C (77 °F) then that would equate to 298.15 K. Different areas assume different standard "room temperature" - but it usually falls between 20 °C (293.15 K) and 30 °C (303.15 K)
add 273 to get from C to K 25 + 273 = 298 Kelvins
17.....you said it in the question.
It is approximately 25°C. In Fahrenheit it is approximately 78°F It is also approximately 298 K
The average surface temperature is 72 K.
Sirius is a binary star. Sirius A has a temperature of about 10,000 K Sirius B has a temperature of about 25,200 K 9,940(a) k 25,200 (b) k 78
the k stands for kelvin, which is another scale for temperature
