135 g metal sample 19.5℃ 100.0℃ 2.50 kJ

 

 

A 135 g sample of a metal requires 2.50 kJ

to change its temperature from 19.5℃ to 100.0℃.

What is the specific heat of this metal?

 

---------------------------------------------------

 

q = C m Δt

( 참고 https://ywpop.tistory.com/2897 )

 

 

 

C = q / m Δt

= 2500 J / [(135 g) (100.0 – 19.5 ℃)]

= 2500 / [(135) (100.0 – 19.5)]

= 0.230 J/g•℃

 

 

 

답: 0.230 J/g•℃
