Determine the specific heat capacity of an alloy that requires 59.3 kJ to raise the temperature of 150.0 g alloy from 298 K to 398 K.

Question

Quizplus · Accepted Answer

The specific heat capacity (c) can be calculated using the formula:

q = mcΔT

where q is the heat energy absorbed by the alloy, m is the mass of the alloy, ΔT is the temperature change, and c is the specific heat capacity.

Substituting the given values, we get:

59.3 kJ = (150.0 g) c (398 K - 298 K)

Simplifying and solving for c, we get:

c = 3.95 J/g°C

Therefore, the specific heat capacity of the alloy is 3.95 J/g°C, which is closest to option C.
