Also I just happening to be learning about this at school
That is the molecular formula of sulfur dioxide
Answer:
C). 373 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit
Explanation:
Kelvin and Celsius are related using the equation K = C + 273.
Celsius and Fahrenheit are related using the equation F = (9/5) * C + 32.
This means that Kelvin and Celsius have to differ by 273, in which only B and C fit that description.
Then you can look at the Celsius and Fahrenheit readings from B and C and apply the equation F = (9/5) * C + 32. For B, you take 0 degrees Celsius and substitute it in for C to get F = (9/5) * 0 + 32, in which you get 32 degrees Fahrenheit and <em>not </em>the 212 degrees in answer B. For C, you do the same: F = (9/5) * 100 degrees Celsius + 32 = 212 degrees Fahrenheit, which does agree with the answer. Therefore, it must only be C.
The distance between (–6, 2) and (8, 10) on a coordinate grid is 8.246
