A cube of ice is taken from the freezer at -8.5°C and placed in a 100 gram aluminumcalorimeter filled with 300 grams of water at a room temperature of 20°C. The final situationis observed to be all water at 17°C. What was the mass of the ice cube? Given the followingvalues: Cice =2100 J/kg/°C, Cwater = 4186 J/kg/°C, Caluminum 920 J/kg/°C, and for waterLe 3.33×105 J/kg and Lv = 22.6×105 J/kg.1

One of a dilute diatomic gas occupying a volume of 10.00 L expands against a constant pressure of 2.000 atm when it is slowly heated. If the temperature of the gas rises by 10.00 K and 400.0 J of heat are added in the process, what is its final volume?
A construction worker uses a steel tape to measure the length of an aluminum support column. If the measured length is 18.700 m when the temperature is 21.2C, what is the measured length when the temperature rises to 29.4C? Note: Dont neglect the expansion of the tape.
Most automobiles have a coolant reservoir to catch radiator fluid than may overflow when 1he engine is hot. A radiator is made of copper and is filled to its 16.0L capacity when at 10.0C. What volume of radiator fluid will overflow when the radiator and fluid reach their 95.0C operating temperature, given that the fluid’s volume coefficient of expansion is =400106/C ? Note that this coefficient is approximate, because most car radiators have operating temperatures of greater than 95.0C.
