Question

If the specific heat capacity of iron is 0.108 cal/g'C. Then how much heat is sufficient to raise the temperature of 1 g of iron through 1'C?

• A. 0.108 calories
• B. 108 calories
• C. 0.0108 calories
• D. 10.8calories

Answer 1

The correct option is A 0.108 calories

Specific is the amount of heat required to raise the temperature of unit mass of substance of through $1^o$. Now it is given that specific heat capacity of iron is $0.108cal./g^{o}C$, it means $0.108cal.$ Heat is sufficient to raise the temperature of $1g$ of iron through $1^{o}C$.
