Answer : The amount of heat needed is, 1188 J
Explanation :
Formula used :
where,
q = heat needed = ?
m = mass of copper = 55 g
c = specific heat capacity of copper = 
= initial temperature = 
= final temperature = 
Now put all the given values in the above formula, we get:
Thus, the amount of heat needed is, 1188 J
360 seconds?
i’m guessing that is the answer as the question is unreasonable
Answer:
1. 374.69 K
Explanation:
Hello,
In this case, pure water's boiling point is 373.15 K, thus by considering the boiling point increase equation:
Whereas i=2 since two ionic species are formed,actually, the experimental value is 2.42 so better work with it, thus:
Thus, the required boiling point is:

Answer:
LEAN DOUGHS
Explanation:
A lean dough is a dough low in fat and sugar. Hard crust breads and rolls such as French and Italian breads and pizza crusts. Other white and whole wheat breads and dinner rolls. These are higher in fat and sugar and sometimes contain eggs and milk solids, because they are richer, they have a softer crust.
