A mixture of nitrogen and argon gas is expanded from a volume of 69.0 L to a volume of 89.0 L, while the pressure is held constant at 55.0 atm. Calculate the work done on the gas mixture. Be sure your answer has the correct sign (positive or negative) and the correct number of significant digits.
A 71.56 gram sample of iron (with a heat capacity of 0.450g) is heated to 100.0 °C. It is then transferred to a coffee cup calorimeter containing 32.5 g of water (specific heat of 4.184/gc) initially at 20.23 °C. If the final temperature of the system is 23.77°C, how much heat was absorbed by the bomb calorimeter? (Please give the absolute value)
In order to find the specific heat capacity of a metal ring that has a mass of 4.5 g you cool it to 273 K and then drop it into a coffee cup containing 3.35 g of water at 305 K. The temperature of the water changes to 301 K. Calculate the specific heat capacity of the metal ring assuming that no heat is lost to the surroundings. The specific heat capacity of water is 4.18 J/g•°C. Answer:
