Answer:
7, 11, 13, 17, 19
All of these numbers only have 1 and themselves as factors, and every other number can be written as a product of two or more primes, making the remaining number composite:

The negative would be 12-14 witch = -2
A: The other related equations would be:
K = °C + 273.15
K = °F + 457.87
<em>Note: There are other equations that can be related, these are just ones that I find to be related. This is open to interpretation. </em>
B:
23° C + 273.15 = 269.15 K
C:
300 K - 273.15 = 26.85 °C
300 Kelvins is greater than 25 degrees Celsius.
