1.5. A refrigerator is used to cool 3 litres of soft drink from room temperature (23 "C) to 5 "C. If the density of the soft drink is 1015 kg/m³ (1 litre = 0.001 m³), how much heat must be removed if the specific heat of the soft drink is 4150 J/kg "C

Calculate the specific heat of a metal (J/ "C g) if the temperature change of a 9.250 g of copper is 172.5 °C; and the temperature change of 72.5 g of water (AT water Is 5.75°C when the hot copper piece is mixed with cold water in the calorimeter. (Water has specific heat of 4.184 J "C g)

In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction. Thermometer Stirring rod A student heats 66.89 grams of platinum to 99.25 °C and then drops it into a cup containing 83.90 grams of water at 22.41 °C. She measures the final temperature to be 24.37.°C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.72 J/°C. Water Assuming that no heat is lost to the surroundings calculate the specific heat of platinum. Metal sample Specific Heat (Pt) =| J/g °C. 02003 Thomeo-BrockaCoe

105 mL of H2 O is initially at room temperature (22.0° C). A chilled steel rod at 2.0° C is placed in the water. If the final temperature of the system is 21.3 °C, what is the mass of the steel bar? Specific heat of water = 4.18 J/g.°C Specific heat of steel = 0.452 J/g.°C
