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;

Hence,the final temp of the gold cube will be 30.773 °C.
