Heat energy is the amount of heat energy in joules gained by a substance when its temperature is raised by 1 degree Celsius per kilogram.
So to find its heat energy we will use the formula Q=mc( delta t)
(NB: im not able to type delta t so to get an idea it is a small triangle with t attached to it indicating change in temperature.
Then we put the values :
Q=(0.026)(500)(22-11)
m_ is mass converted to kilograms
c_ is the specific heat capacity of iron according to Wikipedia it is 500J/kg degree Celsius.
delta t_ is change in temprature
finally we calculate and the answer is
130J .
Heat cause domains of magnets atoms to lose alignment
Answer:
B. metallic
Explanation:
Cu and Fe are metals, so bond between them are metallic.
The answer should be B - lasts longer.
