Answer:
a. chemical change
Explanation:
A chemical change can cause an odor, however a physical change cannot, and the use of thermal energy will only make an object colder, not give it an odor.
Answer:
C) Mass
E) Distance from ground
Explanation:
The factors that influence the gravitational potential energy are mass and distance from the ground or height.
Gravitational potential energy is potential energy of a body in relation to that of another under the influence of gravity.
Mathematically;
Gravitational potential energy = mgh
where m is the mass
g is the acceleration due to gravity
h is the height
