A gas-forming reaction produces 1.90 m of gas against a constant pressure of 176.0 kPa. Calculate the work done by the gas in joules. Hint: be sure to convert the cubic meters to liters and kilopascals to atm. Look up the conversion factors! work: 42
A 1.40-mol sample of hydrogen gas is heated at constant pressure from 304 K to 426 K. (a) Calculate the energy transferred to the gas by heat. kJ (b) Calculate the increase in its internal energy. kJ (c) Calculate the work done on the gas. kJ
A 1.40-mol sample of hydrogen gas is heated at constant pressure from 294 K to 422 K. (a) Calculate the energy transferred to the gas by heat. (b) Calculate the increase in its internal energy (c) Calculate the work done on the gas.
A gas expands from 5.7 L to 8.1 L at constant temperature. Calculate the work done by the gas if it expands against a constant external pressure of 0.98 atm. Answer in units of joules.
A gas expands in volume from 20.5m, to 98.5mt constant temperature. Calculate the work done in joules if the expands against a constant pressure of 0.75atm. 0.09511 051 5.93 -0.0585
2. If the volume of a gas increases by AV (liters) against a constant restraining pressure P (atm), the work transferred from the system (the gas) to its surroundings is PAV (liter atm) a. Work has units of energy but liter atm is not a convenient unit. Show how to convert 1.00 liter atm to joules (J). b. Suppose 201 cal are transferred to a gas in a balloon (as heat) and the gas expands What is the energy balance?...
The volume of a gas decreases from 6 to 2 liters under a constant pressure of one atmosphere. Is the work done by the gas or on the gas? On the gas What work is done? Work Done = Number Joules If the internal energy inceases by 140, what was the net heat exchange? Heat Change = Number Joules
An ideal gas with γ=1.4 occupies 5.0 L at 300 K and 100 kPa pressure and is heated at constant volume until its pressure has doubled. It's then compressed adiabatically until its volume is one-fourth its original value, then cooled at constant volume to 300 K , and finally allowed to expand isothermally to its original state. Find the net work done on the gas in Joules.
11.3 kg of Nitrogen undergoes a constant pressure process at 266.9 kPa. If the gas is contained in a piston-cylinder arrangement and expands from a volume of 0.6 m' to 1.4m3 What is the total amount of work done by the system on its surroundings? ( Answer in kJ to two decimal places, as a positive value.)
Calculate the work done by a system when it expands against a constant external pressure of 4.6 atm from an initial volume of 6.9 L to a final volume of 21.6 L. Give your answer in joules (J) to the nearest integer (whole number). Do NOT input units. If your answer is negative, use a hyphen - (do not use an underscore) and do not add any spaces. For example, if your answer is -345.678 J, enter -346
