A line on a graph has a downward slope
Hello,
The answer should be option D "specific heat".
Reason:
Specific heat is what tells the person how my heat and or pressure is required to raised the objects temperature. Its not option A convection because I'm convection is mainly used as like the ozone layer and the suns rays. Its not option B radiation because radiation doesn't tell the person what temperature it needs in order for it to rise its more like its already rises and hot. Its also not option C because conduction is the process of a object heating another object therefore the answer is option D.
If you need anymore help feel free to ask me!
Hope this helps!
