Question

Heating a 25.0 g sample of each substance below
with 375 J of energy will cause which substance
to have the greatest increase in temperature?
A. copper (specific heat = 0.385 J g-¹° C-¹)
B. gold (specific heat = 0.128 J g-¹ ° C-¹)
C. iron (specific heat = 0.451 J g-¹° C-¹)
D. water (specific heat = 4.184 J g-¹ ° C-¹)
E. Not enough information to determine.

Answer 1

The greatest increase in temperature will be seen in option B. gold (specific heat = 0.128 J g-¹ ° C-¹)

Formula of energy is Q = mcΔt

As we know that mass (m) and energy (Q) is same for all the four options so change in temperature (Δt) is inversely proportional to specific heat (c) of the given substance.

∴ Δt ∝ 1/c

So, as given in the question specific heat for gold is minimum therefore greatest increase in temperature will be seen in gold  

The greatest increase in temperature will be seen in gold (specific heat = 0.128 J g-¹ ° C-¹)
