Hg 25 g 100. J heat energy temp increase

 

 

If 100 J of heat energy is applied to a 25 g sample of mercury,

by how many degrees will the temperature

of the sample of mercury increase?

The specific heat of mercury is 0.14 J/g•℃.

q = C m Δt 이므로,

 

Δt = q / C m

= (100. J) / [(0.14 J/g•℃) (25 g)]

= (100.) / [(0.14) (25)]

= 28.6℃

 

 

 

답: 28.6℃
