A 0.1 kg iron horseshoe that is initially at 726◦C is dropped into a bucket containing 31 kg of water at 24◦C.
What is the final equilibrium temperature? Neglect any energy transfer to or from the surroundings and assume the specific heat of iron is 448 J/kg ·◦ C . The specific heat of water is 4186 J/kg ·◦ C .
Answer in units of ◦C.

A 1.50-kg iron horseshoe initially at 570°C is dropped into a bucket containing 19.0 kg of water at 22.0°C. What is the final temperature of the water–horseshoe system? Ignore the heat capacity of the container and assume a negligible amount of water boils away.
A 1.50-kg iron horseshoe initially at 610°C is dropped into a bucket containing 22.0 kg of water at 26.0°C. What is the final temperature of the water–horseshoe system? Ignore the heat capacity of the container and assume a negligible amount of water boils away. °C
A 0.40-kg iron horseshoe, just forged and very hot (Figure 1), is dropped into 1.15 L of water in a 0.33-kg iron pot initially at 20.0∘C. The value of specific heat for iron is 450 J/kg⋅C∘ , and for water is 4186 J/kg⋅C∘ . If the final equilibrium temperature is 25.0 ∘C, Determine the initial temperature of the hot horseshoe.
A hot iron horseshoe of mass 0.446 kg is dropped into 1.38 kg of water in a 0.328-kg iron pot initially at 20.0°C. If the final equilibrium temperature is 23.8°C, determine the initial temperature of the hot horseshoe. The specific heat of iron is 0.11 kcal/kg °C. Answer: Check
A piece of iron of unknown mass has an initial temperature 210∘C. It is dropped into an aluminum container of mass 0.2 kg containing 1 litre (1.0 kg) of water both of which are at a temperature of temperature 20 ∘C . The final equilibrium temperature of the system when energy transfer between the iron and the water finally stops is 28.5 ∘C. (Assume no thermal energy gets lost.) What is the mass of the iron piece? Express your answer...

At the local county fair, you watch as a blacksmith drops a 0.520-kg iron horseshoe into a bucket containing 26.5 kg of water. If the initial temperature of the horseshoe is 454°C, and the initial temperature of the water is 23.1°C, what is the equilibrium temperature of the system? Assume no heat is exchanged with the surroundings. Do not enter unit. b) Suppose the 0.520-kg iron horseshoe had been a 1.07-kg lead horseshoe instead. What would the equilibrium temperature be...
A 1.00-kg iron horseshoe is taken from a forge at 900°C and dropped into 4.00 kg of water at 10.0°C. Assuming that no energy is lost by heat to the surroundings, determine the total entropy change of the horseshoe-pluswater system.
