. 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?

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

Question was not very clear if there are specific answer choices tell me and i'll try to you more. hope this though2 laps is 1 min. we know that for each min she does two times the amount of laps. for 12 laps we can do 12/2 which does give us 12 laps in 6 mins not 16 mins.
