The answer would have to be d because heat rises
Answer:
Because you have to give the simplest ratio of equation. Equation I can be simplified by dividing all the coefficients by 2 to make it into equation II.
*Every equation has to be in the simplest form of coefficients.
Ratio of Equation I :
2 : 4 : 2 : 4
Ratio of Equation II :
1 : 2 : 1 : 2
