Problem: Which sample is most likely to undergo the smallest change in temperature upon the absorption of 100 kJ of heat?a) 15 g waterb) 15 g leadc) 50 g waterd) 50 g lead

FREE Expert Solution

q=mc∆T

  • c for lead = 0.128 J/(g•oC)
  • c for water = 4.18 J/(g•oC)


for same q: 

  • Higher mass, m and higher specific heat capacity, c → lower ΔT
