If the temperature of a room is 333.4 kelvin, determine the room’s temperature in degrees Celsius.
00:00:11.080 --> 00:00:13.080
So first of all, we need to see, well, what is kelvin.
00:00:13.440 --> 00:00:15.440
Well, kelvin is another measure of temperature.
00:00:17.080 --> 00:00:30.040
And kelvin is often used when we’re looking at absolute zero because absolute zero is zero on the kelvin scale but negative 273.15 on the degrees Celsius scale.
00:00:31.840 --> 00:00:34.440
An absolute zero is the lowest temperature possible.
00:00:35.360 --> 00:00:39.280
At a temperature of absolute zero, there’s no motion and no heat.
00:00:39.800 --> 00:00:42.080
So, it’s the lowest possible temperature we can have.
00:00:44.040 --> 00:00:56.240
And therefore, if we surmise that zero is negative 273.15 when looking at degrees Celsius, then if we had zero degrees Celsius, this would be equal to 273.15 kelvin.
00:00:58.240 --> 00:01:05.240
And 100 degrees Celsius, which is the boiling point of water, is gonna be equal to 373.15 kelvin.
00:01:05.520 --> 00:01:06.040
Okay, great.
00:01:06.440 --> 00:01:10.360
So now we’ve got an understanding of what kelvin is, let’s try and solve the problem.
00:01:12.040 --> 00:01:17.080
Well, in the problem, what we’re trying to do is convert from kelvin to degrees Celsius.
00:01:17.560 --> 00:01:19.360
Well, to do that, we have a little formula.
00:01:19.720 --> 00:01:27.080
And that is that the temperature in degrees Celsius is equal to the temperature in kelvin minus 273.15.
00:01:27.640 --> 00:01:33.040
And we get that because we know that the absolute zero is equal to negative 273.15.
00:01:34.880 --> 00:01:40.920
It’s also worth noting at this point that kelvin is not measured in degrees, so we don’t have degrees kelvin.
00:01:40.920 --> 00:01:45.400
We have degrees Celsius or degrees Fahrenheit, but kelvin we just write as a number.
00:01:47.400 --> 00:01:59.640
So now, if we substitute in the values we know, we’ll get the temperature in degrees Celsius is equal to 333.4 minus 273.15, which is gonna give us 60.25.
00:02:01.160 --> 00:02:09.720
So therefore, in answer to the question, we can say that 333.4 kelvin is equal to 60.25 degrees Celsius.
