A 61.93 gram sample of iron (with a specific heat of 0.450 J/g °C) is heated to 100.0 °C. It is then transferred to a coffee cup calorimeter containing 40.6 g of water (specific heat of 4.184 J/ g °C) initally at 20.63 °C. If the final temperature of the system is 23.59, what was the heat absorbed (q) of the calorimeter? (total heat absorbed by the water and calorimeter = heat released by the iron)

The specific heat of iron is 0.450 J/g°C 1127 Chapter 6 Discussion Problems 1. How much energy must be transferred to raise the temperature of a cup of coffee (250 mL) from 20.5°C 10 95.6°C? Assume density and specific heat is the same as Water 4.16 Ig/ml 2. An 38.5 g piece of iron with temperature 78.8°C is placed in a beaker containing 244 g of water at 18.8°C. When thermal equilibrium is reached, what is the final temperature? Assume...
A 60.80 gram sample of iron (with a heat capacity of 0.450 J/g◦C) is heated to 100.00 ◦ It is then transferred to a coffee cup calorimeter containing 52.42 g of water (specific heat of 4.184 J/ g◦C) initially at 20.47 ◦C. If the final temperature of the system is 28.78, what was the heat gained by the calorimeter? If the calorimeter had a mass of 25.19 g, what is the heat capacity of the calorimeter?
A 56 gram sample of iron (with a heat capacity of 0.450 J/g ºC) is heated to 100.0 ºC. It is then transferred to a coffee cup calorimeter containing 40.35 g of water (specific heat of 4.184 J/ g ºC) initially at 20.63 ºC. If the final temperature of the system is 23.59, how much heat was absorbed by the calorimeter? Record your answer as a whole number (assume the sign is positive).
