Question

The specific heat of water is 4.18 J/(gi°C) and that of wood is 1.97 J/(gi°C). Which statement is correct?
Regardless of mass, wood will heat up less than water if the same heat is added.
Given equal masses, wood will heat up less than water if the same heat is added.
Given equal masses, water will heat up less than wood if the same heat is added.
Regardless of mass, water will heat up less than wood if the same heat is added.

Answer 1

Given equal masses, water will heat up less than wood if the same heat is added.

Reason: ΔT = Q/(m c). Water's specific heat (4.18 J/g°C) is larger than wood's (1.97 J/g°C), so for the same Q and m, ΔT for water is smaller.
