Answer :
The final temp of the gold cube will be 30.773 °C. The heat absorption principle is used in the given problem.
What is specific heat capacity ?
The amount of heat required to increase a substance's temperature by one degree Celsius is known as specific heat capacity.
Similarly, heat capacity is the relationship between the amount of energy delivered to a substance and the increase in temperature that results.
Mathematically, specific heat capacity is given by;
\rm Q= Ms \triangle t
Where,
Q is the amount of energy necessary to raise the temperature
M is the mass
Δt is the time it takes to raise the temperature.
s stands for specific heat capacity
While t stands for temperature change.
The given data in the problem is;
The energy required to raise the temperature is 430 joules.
M is the mass of gold = 250 g
s is the specific heat capacity of silver= (0.3 J/°Cg),
ΔT is the temperature fluctuation
The specific heat capacity is given by;
[tex]\rm Q= Ms \triangle t \\\\ \rm 430= 250 \times 0.3 \times (T_f-25)\\\\ T_f=30.773 ^0 C[/tex]
Hence,the final temp of the gold cube will be 30.773 °C.
