The specific heat of iron is 0.11 cal /g·°C. What will be the final temperature if 275 calories are added to a 75.0 piece of iron initially at 25°C?

Explanation:

The expression for the calculation of the enthalpy change of a process is shown below as:-

Where,  

 is the enthalpy change

m is the mass

C is the specific heat capacity

 is the temperature change

Thus, given that:-

Mass  = 75.0 g

Specific heat = 0.11 cal/g°C

Heat added = 275 calories

So,  

Solving, we get that:-

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /
