Answer: Option (A) is the correct answer.
Explanation:
Specific heat is defined as the amount of heat needed to raise the temperature by one degree celsius.
Mathematically, Q = [tex]mC \Delta T[/tex]
where Q = heat absorbed
m = mass
C = specific heat
[tex]\Delta T[/tex] = change in temperature
Therefore, in 1 kg there are 100 grams so, 10 grams equal 0.01 Kg. Thus, calculate the specific heat value as follows.
Q = [tex]mC \Delta T[/tex]
100 joules = [tex]10 g \times C \times 20^{o}C[/tex]
C = 0.5 [tex]J/g ^{o}C[/tex]
Thus, we can conclude that specific heat of the given metal is 0.5 [tex]J/g ^{o}C[/tex].
