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 (mass = 0.45 kg ), just forged, is dropped into 1.40 L of water in a 0.50 kgiron pot initially at 21.0 ∘C. If the final equilibrium temperature is 31.0 ∘C, estimate the initial temperature of the hot horseshoe. Express your answer using two significant figures. T = ∘C

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 0.320 kg iron horseshoe that is initially at 400°C is dropped into a bucket containing 18.0 kg of water at 21.8°C. What is the final equilibrium temperature (in °C)? Neglect any heat transfer to or from the surroundings. Do not enter units.
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 copper pot with a mass of 0.500 kg contains 0.170 kg of water, and both are at a temperature of 20.0 ∘C . A 0.250 kg block of iron at 85.0 ∘C is dropped into the pot. Find the final temperature of the system, assuming no heat loss to the surroundings.
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...
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.
