Answer:
For this case, if we try to find the final temperature of A and B, we see that we will obtain an expression in terms of specific heats and masses, from the information given we know the relationship between specific heats, but we don't know the relationship that exists among the masses, then the best option for this case is:
d) More information is needed
(The relation between the masses is not given)
Explanation:
For this case we know the following info:
Where c means specific heat for the substance A and B.
We also know that the initial temperatures for both sustances are equal:
We assume that we don't have melting or vaporization in the 2 substances. So we just have presence of sensible heat given by this formula:
And for this case we know that Both A and B are at the same initial temperature when equal amounts of energy are added to them, so then we have this:
And if we replace the formula for sensible heat we got:
And if we replace for the change of the temperature we got:
And since we have this:
For this case, if we try to find the final temperature of A and B, we see that we will obtain an expression in terms of specific heats and masses, from the information given we know the relationship between specific heats, but we don't know the relationship that exists among the masses, then the best option for this case is:
d) More information is needed
(The relation between the masses is not given)
