Given:
Specific Heat (c) values :-
Al = 0.897 J/gC
Ag = 0.234 J/gC
Fe = 0.450 J/gC
Zn = 0.387 J/gC
Mass of all element = 10 g
Initial temperature T1 = 25 C
Final temperature T2 = 90 C
To determine:
The order in which the elements will reach 90 C
Explanation:
The heat (Q) absorbed by the elements is mathematically expressed as:
Q = mcΔT
where: m = mass of the substance
c = specific heat, which is the amount of heat required to raise the temperature of a unit mass of the substance by a unit degree
ΔT = change in temperature
In the given examples, m = 10 g for all elements and ΔT = 90-25 = 65 C is also the same
Therefore, the heat absorbed (Q) will depend only on the specific heat of the elements. Lower the value of the specific heat, lower is the amount of heat required to raise the temperature to 90 C and the element will heat up faster.
Based on the values of the specific heats, the order in which the samples would reach 90 C from the first to the last would be:
Ag, Zn, Fe, Al
Answer:
B. Ag, Zn, Fe, Al
