Question

21.6 J of energy are used to heat a 2.0 g piece of iron from 5.0oC to 29.0oC. What is the experimental specific heat capacity of iron in J/ (g . oC) ?

ANSWER QUICKLY PLEASE!

Answer 1

Answer: 0.45 J / g °C

Explanation: solution attached.

Heat is equal to the product of mass, specific heat and change in temperature.

Q= mc∆T

Derive the equation to find c

c = Q / m∆T substitute the values

c = 21.6 J / 2.0g ( 24°C - 5°C)

c = 0.45 J / g ° C
