An electric range burner weighing 693.0 grams is turned off after reaching a temperature of 497.6°C, and is allowed to cool down to 22.9°C. Calculate the specific heat of the burner if all the heat evolved from the burner is used to heat 559.0 grams of water from 22.9°C to 80.2°C. Answer J/gºC
In the laboratory a student uses a "coffee cup" calorimeter to determine the specific heat of a metal. She heats 19.6 grams of gold to 98.59°C and then drops it into a cup containing 84.0 grams of water at 20.58°C. She measures the final temperature to be 21.16°C. Assuming that all of the heat is transferred to the water, she calculates the specific heat of gold to be J/g°C.
In the laboratory a student uses a "coffee cup" calorimeter to determine the specific heat of a metal. She heats 19.3 grams of chromium to 98.38°C and then drops it into a cup containing 83.1 grams of water at 22.04°C. She measures the final temperature to be 23.83°C. Assuming that all of the heat is transferred to the water, she calculates the specific heat of chromium to be J/gºC.
