Answer

See explanation below.

Work Step by Step

q = c x mass x ΔT In this situation, all of the samples have the same mass, 50. g, so mass is not a variable. All also have the same q value, 450. J. So, 450. J α c x mass. c, specific heat capacity, and ΔT are inversely proportional. The higher the ΔT, the lower the value of specific heat capacity: ΔT: B > D > C > A Specific heat capacity: B < D < C < A
