Question

The Heat (H) required to melt copper is proportional to the copper’s mass in grams (g). Suppose the number of calories to melt 1 gram of copper is represented by c . Which statements are true for this situation

Answer 1

H = cg The number of calories to melt one gram is the constant of proportionality. Heat = calories(mass) Write as y = kx, where k is the constant of proportionality → H = cg → c is the constant of proportionality

Explanation:

Answer 2

The correct statements for this situation are:

B) H=cg

E) The number of calories to melt one gram is the constant of proportionality.

In a proportional relationship, the equation takes the form

y=kx, where

k is the constant of proportionality. In this scenario, the heat (H) required to melt copper is proportional to the mass of copper (g), and the number of calories to melt 1 gram of copper is represented by

c. Therefore, the correct equation is

H=cg,

where c is the constant of proportionality.

Option E is also true because in the given scenario, c represents the number of calories required to melt one gram of copper, and it is the constant of proportionality in the relationship between H and g.
