Question

. A 2 kg block of iron is given 10 KJ of energy and its temperature rises by 10 °C. What is the specific heat capacity of the iron? ​

Answer 1

heat capacity = 500J/kg• K

Step-by-step explanation:

q = m•c•ΔT

q = heat energy

m = mass

c = heat capacity

ΔT= change in temperature

10KJ = 10000 J

10000 J = 2kg • c • 10 Cº

divide each side by 20

500J/kg• K = heat capacity

Answer 2

Let’s take Specific Capacity of Iron as “x”

Solution:

Q=c*m*change in temperature

10000=x*2*10

x=500

Specific Heat Capacity of the Iron is 500 J/kg*C
