A 110. g sample of copper (specific heat capacity= 0.20 J/g C) is heated to 82.4 C and then placed in a container of water at 22.3 C. The final temperature of the water and copper is 24.9 C. What is the mass of the water in the container, assuming that all the heat lost by the copper is gained by the water?
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?
Specific Heat Capacity A 21.5-g sample of an unknown metal is heated to 94.0°C and is placed in a insulated container containing 128 g of water at a temperature of 21.4°C. After the metal cools, the final temperature of the metal and water is 25.0°C. Calculate the specific heat capacity of the metal, assuming that no heat escapes to the surroundings. Heat loss=Heat gained. Specific Heat Capacity of water is 4.18 J/g/K in this temperature range. Submit Answer Incompatible units....
2. (15 pts) A 83.5 g sample of a metal alloy is heated to 88.1°C and it is then placed in a coffee-cup calorimeter containing 30.0 g water at 15.0°C. The final temperature of the metal + water is 25.3 °C. Calculate the specific heat of metal alloy, in J/(g°C), assuming no heat escapes to the surroundings or is transferred to the calorimeter. The specific heat of water is 4.184 J/(g°C).
Calculating specific heat capacity A constant-pressure calorimeter is often used to find the specific heat capacity of a substance if it is not known. A known mass of the substance can be heated and added to water of known mass and initial temperature. Since the specific heat capacity of water is known ( C s,water =4.184J/(g⋅ ∘ C)) , the amount of heat transferred to the water can be calculated by measuring the final temperature of the mixture at thermal...
