Answer:

1. The final temperature of the metal is 111 °C.

2. The change in the temperature of the water is 6.2 °C

3. The change in the temperature of the metal is 40.6 °C.

Explanation:

From the question given above, the following data were obtained:

Initial temperature of metal (Tₘ₁) = 70.4 °C

Initial temperature of water (Tᵥᵥ₁) = 23.6 °C

Equilibrium temperature (Tₑ) = 29.8 °C

1. Determination of the final temperature of metal.

We'll begin by calculating the change in temperature of the metal. This can be obtained as follow:

Initial temperature of metal (Tₘ₁) = 70.4 °C

Equilibrium temperature (Tₑ) = 29.8 °C

Change in temperature of metal (ΔTₘ) =?

ΔTₘ = Tₘ₁ – Tₑ

ΔTₘ = 70.4 – 29.8

ΔTₘ = 40.6 °C

Finally, we shall determine the final temperature of the metal. This can be obtained as follow:

Initial temperature of metal (Tₘ₁) = 70.4 °C

Change in temperature of water (ΔTₘ) = 40.6 °C

Final temperature of metal (Tₘ₂) =?

40.6 = Tₘ₂ – 70.4

Collect like terms

40.6 + 70.4 = Tₘ₂

111 = Tₘ₂

Tₘ₂ = 111 °C

Thus, the final temperature of the metal is 111 °C

2. Determination of the change in the temperature of the water.

Initial temperature of water (Tᵥᵥ₁) = 23.6 °C

Equilibrium temperature (Tₑ) = 29.8 °C

Change in temperature of water (ΔTᵥᵥ) =?

ΔTᵥᵥ = Tₑ – Tᵥᵥ₁

ΔTᵥᵥ = 29.8 – 23.6

ΔTᵥᵥ = 6.2 °C

Therefore, the change in the temperature of the water is 6.2 °C

3. Determination of the change in the temperature of the metal.

The change in the temperature of the metal is 40.6 °C.
