Consider a mixture of air and gasoline vapor in a cylinder with a piston. The original volume is 45 cm³. If the combustion of this mixture releases 936 J of energy, to what volume (in L) will the gases expand against a constant pressure of 659 torr if all the energy of combustion is converted into work to push back the piston? L Need Help? Read It Supporting Materials Periodic Table Constants & Factors Supplemental Data

What is the change in internal energy of the air within the piston?   The air within a piston equipped with a cylinder absorbs 555 J of heat and expands from an initial volume of 0.10 L to a final volume of 0.87 Lagainst an external pressure of 1.0 atm.

A gas expands and its pressure and volume are recorded, as shown above. What is the work done by the gas? (see picture attached)    A. 130 J B. -13,172 J C. 13,172 J D. -130 J

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…

A typical bike tire has a volume of 150 in³. If a bicycle pump can hold 567 cm³ of air, and you compress it to 350 cm³ with each pump, against an external pressure of 1.0 atm, how much total work (J) would you need to do on the gas in the bicycle pump in order to completely fill the tire? Give your answer as a positive value. Type your numeric answer and submit

thermor A 59.1 g sample of brass, which has a specific heat capacity of 0.375 J-g that contains 100.0 g of water. The temperature of the water starts off at 17.0 °C. When the temperature of the water stops , is put into a calorimeter (see sketch at right) insulate containe water changing it's 20.5 °C.

The question is given like this, it is not incomplete. There is no heat capacity of the calorimeter given. Can it be solved without that? It is high school chemistry so maybe it can be solved in an easier way? Many thanks.

A sample of gass occupies a volume of 56.4mL. As it expands, it does 133.3J of work on its surroundings at a constant pressure of 783 torr. What is the final volume of gas?

Q2: An ideal gas is compressed from 6.0 L to 2.0 L by a constant external pressure of 4.0 atm. How much work (in KJ) is done on the gas? Q3: A 20.0 mL sample of a gas is at 7.00 atm of pressure and a temperature of 289 K. What volume (ml) would the gas occupy at STP?
