At a festival, spherical balloons with a radius of 220. cm are to be inflated with hot air and released. The air at the festival will have a temperature of 25 °C and must be heated to 100 °C to make the balloons float. 1.00 kg of propane (C3Hg) fuel are available to be burned to heat the air. Calculate the maximum number of balloons that can be inflated with hot air. Here are some data you may find useful: Specific heat capacity of air: Density of air at 100 °C: Density of propane at 100 °C: balloons Explanation 1.009 Formation enthalpy of propane at 25 °C: - 103.8 Recheck 0.946 X 1.440 J g-°C kg 3 m Any other data you need should be taken from the ALEKS Data resource. kg 3 m kJ mol S © 2023 McGraw Hill LLC.

A chunk of platinum weighing 19.36 grams and originally at 98.22 °C is dropped into an insulated cup containing 77.94 grams of water at 21.09 °C. Thermometer Water Metal- sample Stirring rod 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. Using the accepted value for the specific heat of platinum (See the References tool), calculate the final temperature of the water. Assume that no heat is lost to the surroundings. Tfinal = °℃
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.A chunk of lead weighing 19.61 grams and originally at 97.01 °C is dropped into an insulated cup containing 82.14 grams of water at 21.79 °C.The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.61 J/°C.Using the accepted value for the specific heat of lead (See the References tool), calculate the final temperature of the water. Assume that no heat is lost to the surroundings.
A 45.90 g sample of pure copper is heated in a test tube to 99.40°C. The copper sample is then transferred to a calorimeter containing 61.04 g of deionized water.

You're tasked with verifying whether or not a platinum ring bought from an online store is indeed made of platinum. After checking that the ring is not plated, but a solid piece of metal, you test the specific heat using a calorimeter. You heat up the 15.00 g ring in a water bath which is brought to a boil for 15 minutes. Then, you quickly transfer the ring into your calorimeter which has 100.0 g of water initially at 21.00 degrees Celsius. The ring and the calorimeter equilibriate at a final temperature of 21.69 degrees Celsius. According to your calorimetric test and table 2, what is the identity of the metal in the ring? The specific heat of water is 4.184 J/ (g*C).
