Question

Hot water heaters often have warning labels indicating that injuries can result when the temperature of the water is above 125°F. What is this temperature in degrees Celsius and in kelvins?

3.The temperature at Earth’s center is estimated to be about 5,100 K. Express this temperature in both degrees Celsius and degrees Fahrenheit.

please please help me 10 points for the first answer

Answer 1

It may be better to know where the answers came from... so you can do it again:

To convert F to C, you simply take the F, subtract 32 and divide by 1.8... so you end up with:

(125-32)/1.8 = 51.67 C

To convert from C to Kelvins, you just take the C temperature and add 273.15 (most sources forget the .15 at the end, but it's important for any sort of precise work)... so you get:

51.67+273.15 = 324.83 Kelvin

Applying the same logic (in reverse) to 5100 K you get:

5100 K - 273.15 = 4826.85 C (you just subtract 273.15 from the K temperature)

To get F, you multiply the C temperature by 1.8 and then add 32, so you get:

(4826.85*1.8)+32 = 8720.33 F

Technically, since the first temperature was given in to three significant figures your final answer should be: 51.7 C

... and the second temperature was given to 4 significant figures so your answer should be: 8720 F.

Answer 2

125°F = 51.667°C = 324.82

5100°K = 8720.3°F = 4,826.8°C

Answer 3

125F

51.6C

324.6 K

5100 K

8,720.6F

4827C
