Question
A coffee-cup calorimeter containing 100 grams of water is measured to have an initial temperature of 28 degrees Celsius. An unknown metal weighing 8.0 grams is heated to a temperature up to 150 degrees Celsius and then immediately dropped into the coffee cup calorimeter filled with the water. The final temperature of the set-up is recorded to be 32.5 degrees Celsius. Assume no heat is lost to the surroundings nor absorbed by the coffee-cup calorimeter.
a. The amount of heat absorbed by 100-grams of water in the coffee-cup calorimeter is ___ KiloJoules.
b. The specific heat capacity of the unknown metal is ___ Joules/gram-degree Celsius.

- A student is using a calorimeter to determine the specific heat of a metallic sample. She measures out 128.1 grams of her metal and heats it to 79.6 degrees Celsius. Then, she puts the sample into a calorimeter containing 11.47 grams of water at 45.7 degrees Celsius. She measures the temperature of the water in the calorimeter until the number stops changing, then records the final temperature to be 71.4 degrees Celsius. What is the specific heat of the metal? Please answer to three digits after the decimal point.arrow_forwardA hot 105.9 g lump of an unknown substance initially at 154.0 °C is placed in 35.0 mL of water initially at 25.0 °C and the system is allowed to reach thermal equilibrium. The final temperature of the system is 36.2 °C. Using this information and the specific heat values for several metals in the table, identify the unknown substance.
