An ideal gas expands in a reversible and adiabatic process. What will happen to the temperature of the gas? Question 12 options: The temperature will rise The temperature will fall There will be no change in temperature The final temperature will be zero

A mixture of xenon and argon gas is compressed from a volume of 81.0 L to a volume of 69.0 L, while the pressure is held constant at 77.0 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.

Why do people use Calorimetry and discuss it's applications in the medical or engineering world.

A leaky balloon loses gas until it drops from a volume of 9.8 L to 1.5 L. If it started with 0.402 mol of helium gas, how many moles of helium gas remain in the balloon after it has finished leaking? Assume temperature and pressure stay constant. Answer with three sig figs and show all work.

Ignition wires heat Thermometer Stirrer A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of sample fuels and the energy content of foods. In an experiment, a 0.5650 g sample of quinizarin (C14H804) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.187×103 g of water. During the combustion the temperature increases from 23.98 to Water 26.55 °C. The heat capacity of water is 4.184 J gloC1. The heat capacity of the calorimeter was determined in a previous experiment to be 770.8 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of quinizarin based on these data. C14H804(s) + 1402(g) → 4 H20(1) + 14 CO2(g) + Energy Sample dish Burning sample Steel bomb Insulated outside chamber Molar Heat of…

1.) In a hypothetical garden each of the identical trees consist of 11 branches and each branch on a tree consists of 35 leaves. How many trees would have 8,085 leaves? (Do not give units in answer.) 2.) Supposing in a hypothetical garden 43 identical trees contain a total of 19,565 leaves. If each branch on a given tree consist of 35 leaves how many branches does each tree have? (Do not give units in your answer.)

6:17 AM Wed Jan 25 Question 26.b of 28 A 8.65 g sample of an unknown salt (MM = 116.82 g/mol) is dissolved in 150.00 g water in a coffee cup calorimeter. Before placing the sample in the water, the temperature of the salt and water is 23.72 °C. After the salt has completely dissolved, the temperature of the solution is 28.54 °C. What is the change in temperature, in °C, inside the calorimeter? Tap here or pull up for additional resources 1 4 7 +/-
