:  how much energy is required to heat an iron nail with a mass of 25.5 grams from 65°c until it becomes red hot at 720°c? (c  for iron = 0.4494 j/g°c).  part a:   enter the variable symbol for the quantity you need to find.  use your keyboard and the keypad to enter your answer.  then click done.

Q = mct  

-Q= energy in Joules  

-m = mass in grams  

-c= specific heat capacity in J/g degree C  

-t = delta temperature in degrees Celsius  

So,  

Q = m c t  

Q = (7 grams)(0.448J/g C)(750 C - 25 C)  

Q = 2273.6 J  

Your final answer = 2273.6 Joules

passed in september 1935, these laws are known as nuremberg laws.   they forbid jews from marrying but not directly forced them to divorce aryans. what is most noticeable is the fact that the jews were defranchised, meaning by this that they were not expected to have any civil rights, including the right to vote. the right answer is deprived of the right to vote.
