#238Jcolor(white)(x)kg^(-1)color(white)(x)K^(-1)#

Explanation:

To find the specific heat capacity, we have to rearrange this equation:
#DeltaE=mcDeltatheta#, where

  • #DeltaE# = change in energy (#J#)
  • #m# = mass (#kg#)
  • #c# = SHC (#J# #kg^(-1)# #K^(-1)#)
  • #DeltaT# = temperature change (#K#)

#c=(DeltaE)/(mDeltatheta)#

As #Delta1^circC-=Delta1K#, #Deltatheta=10K#

#1.25kJ=1250J#

#525g=0.525kg#

#c=1250/(10*0.525)=1250/5.25~~238.1~~238Jcolor(white)(x)kg^(-1)color(white)(x)K^(-1)#
