To determine the specific heat of an object, a student heats it to 100 ∘C in boiling water. She then places the 87.2 g object in a 173 galuminum calorimeter containing 136 g of water. The aluminum and water are initially at a temperature of 19.8 ∘, and are thermally insulated from their surroundings. If the final temperature is 23.4 ∘, what is the specific heat of the object? Referring to the table, identify the material in the object. 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)

A 309 g block of copper at a temperature of 73.0°C is dropped into 579 g of water at 26.9°C. The water is contained in a 118 g glass container. Assume the glass has the same initial temperature as the water (26.9°C). What is the final temperature of the mixture? The specific heat of copper is 387 J/kg˚C, the specific heat of water is 4186 J/kg˚C, and the specific heat of glass is 837 J/kg˚C.

The specific heat c is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00°C. The specific heat c is a property of the substance; its Sl unit is J/(kg · K) or J/(kg.°C). Recall that the temperature change (AT) is the same in units of kelvin and degrees Celsius. water silver copper cup Case 1: A 0.780-kg silver pellet with a temperature of 85 °C is added to 0.150 kg of water in...

In the laboratory a student determines the specific heat of a metal as follows: He heats 18.4 grams of tungsten to 98.08 °C and then drops it into a cup containing 77.7 grams of water at 21.47 °C. When thermal equilibrium is reached, he measures the final temperature to be 22.03 °C. Assuming that all of the heat from the metal is transferred to the water, he calculates the specific heat of tungsten to be J/g°C.
