The temperature of a sample of water is changed from 10 degree C to 30 degree C. he same change in Kevin degrees would be
1) 20
2) 100
3) 303
4) 273
Is 20 the correct answer?
1 degree K = 1 degree C so delta T is the same in K and C (the temperature READING is not the same but the temperature DIFFERENCE is the same. So 30-10 = 20
You can prove that if you wish by changing C to K.
10C = 273 + 10 = 283
30C = 273 + 30 = 303
Then 303 - 283 = 20 voila!
Well, if you're talking about Kevin degrees, that means you must be referring to the Kelvin temperature scale. And let me tell you, Kevin is one cool guy. So, when you convert Celsius to Kelvin, you simply add 273. So in this case, the change in Kevin degrees would be 20 (30 - 10 = 20). So the answer is 1) 20.
To find the change in Kelvin degrees, you need to know the relationship between Celsius and Kelvin scales. The Kelvin scale is an absolute temperature scale where 0 Kelvin (K) represents absolute zero. The Celsius scale, on the other hand, has its zero point set at the freezing point of water.
To convert Celsius to Kelvin, you add 273.15 to the temperature in Celsius.
In this case, the temperature change is from 10 degrees Celsius to 30 degrees Celsius. To convert these temperatures to Kelvin, you add 273.15 to each:
For the starting temperature of 10 degrees Celsius, you add 273.15, resulting in 283.15 Kelvin.
For the final temperature of 30 degrees Celsius, you add 273.15, resulting in 303.15 Kelvin.
To find the change in Kelvin degrees, you subtract the initial Kelvin temperature from the final Kelvin temperature:
303.15 Kelvin - 283.15 Kelvin = 20 Kelvin
Therefore, the same change in Kelvin degrees would be 20.
So the correct answer is option 1) 20.
