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...

An unknown substance has a mass of 16.7 g. The temperature of the substance increases by 13.7∘ C when 53.8 J of heat is added to the substance. The table lists the specific heats of select substances lead 0.128 silver 0.235 copper 0.385 iron 0.449 aluminum 0.903 water 4.184 What is the most likely identity of the unknown substance?

In the specific heat capacity experiment, the unknown object has a mass of 0.073 kg and was cooled to -9 C. Then, it was placed in a calorimeter (mcalorimeter = 0.11 kg) that contain water (mwarter = 0.23 kg) at a temperature of 26 C. After 5 minutes the temperature dropped to 22.4 C. Determine the specific heat capacity of the unknown object. (cwater = 4186 J/kg. C and ccalorimeter = 900 J/kg. C)

1. Zinc has a specific heat of 0.39 J/g°C while iron has a specific heat of 0.45 J/g°C. If a 100g sample of each metal is cooled from 100°C to room temperature (25°C), which one releases more heat energy? 2. An engineer tests the thermal properties of a metal alloy. Using a 50.0 g alloy sample, she finds that adding 487 J of heat energy to the alloy causes a temperature change of 4.10°C. What is the specific heat of...

In the specific heat capacity experiment, the unknown object has a mass of 0.070 kg and was cooled to -3C. Then, it was placed in a calorimeter (mcalorimeter = 0.13 kg) that contain water (mwarter = 0.26 kg) at a temperature of 26 oC. After 5 minutes the temperature dropped to 24C. Determine the heat lost by the water. (cwater = 4186 J/kg. C and ccalorimeter = 900 J/kg. C)
