Problem Analysis

To find the specific heat capacity of the material from which the metal part was made, we can use the formula:

Q = mcΔT

Where: - Q is the heat transferred - m is the mass of the metal part - c is the specific heat capacity of the material - ΔT is the change in temperature

We know the mass of the metal part (300 grams), the mass of the water (600 grams), and the initial and final temperatures of both the water and the metal part. We can use this information to calculate the specific heat capacity of the material.

Calculation

Let's calculate the heat transferred to the water and the metal part separately and then equate them to find the specific heat capacity.

Heat transferred to the water: The heat transferred to the water can be calculated using the formula:

Q_water = m_water * c_water * ΔT_water

Where: - Q_water is the heat transferred to the water - m_water is the mass of the water (600 grams) - c_water is the specific heat capacity of water (4.18 J/g°C) - ΔT_water is the change in temperature of the water (25°C - 22°C = 3°C)

Substituting the values, we get:

Q_water = 600 g * 4.18 J/g°C * 3°C

Q_water = 7536 J

Heat transferred to the metal part: The heat transferred to the metal part can be calculated using the formula:

Q_metal = m_metal * c_metal * ΔT_metal

Where: - Q_metal is the heat transferred to the metal part - m_metal is the mass of the metal part (300 grams) - c_metal is the specific heat capacity of the material (unknown) - ΔT_metal is the change in temperature of the metal part (25°C - initial temperature of the metal part)

We need to find the value of ΔT_metal, which is the change in temperature of the metal part. To do that, we need to know the initial temperature of the metal part.

Missing Information

The problem statement does not provide the initial temperature of the metal part. Without this information, we cannot calculate the specific heat capacity of the material. Please provide the initial temperature of the metal part so that we can proceed with the calculation.
