  1. A gas expands from an initial volume of 2 L to a final volume of 8 L while absorbing 100 J of heat. Calculate the work done by the gas during this process.
  2. A sample of gas undergoes an isothermal compression at a constant temperature of 300 K. If the gas releases 200 J of heat during this process, calculate the work done by the gas.
  3. A heat engine operates between two reservoirs at temperatures of 400 K and 100 K. If the engine absorbs 500 J of heat from the hot reservoir, calculate the maximum possible work output of the engine.
  4. A refrigerator operates between two reservoirs at temperatures of 300 K and 250 K. If the refrigerator requires 100 J of work input, calculate the amount of heat extracted from the cold reservoir.
  5. A gas undergoes an adiabatic expansion, during which its volume increases by a factor of 4. If the initial temperature of the gas is 400 K, calculate the final temperature of the gas.
  6. A sample of gas undergoes an isochoric process, during which it absorbs 300 J of heat. If the initial temperature of the gas is 200 K, calculate the final temperature of the gas.
  7. A heat engine operates between two reservoirs at temperatures of 500 K and 200 K. If the engine has an efficiency of 40%, calculate the amount of heat absorbed from the hot reservoir.
  8. A gas undergoes a reversible isothermal expansion at a constant temperature of 300 K. If the gas does 200 J of work during this process, calculate the amount of heat absorbed by the gas.
  9. A sample of gas undergoes an isobaric process, during which it releases 400 J of heat. If the initial pressure of the gas is 2 atm, calculate the final pressure of the gas.
  10. A heat engine operates between two reservoirs at temperatures of 600 K and 300 K. If the engine has an efficiency of 50%, calculate the amount of heat absorbed from the hot reservoir.
  11. A gas undergoes an adiabatic compression, during which its pressure increases by a factor of 3. If the initial temperature of the gas is 500 K, calculate the final temperature of the gas.
  12. A sample of gas undergoes an isochoric process, during which it releases 200 J of heat. If the initial temperature of the gas is 400 K, calculate the final temperature of the gas.
  13. A heat engine operates between two reservoirs at temperatures of 400 K and 200 K. If the engine absorbs 800 J of heat from the hot reservoir, calculate the maximum possible work output of the engine.
  14. A refrigerator operates between two reservoirs at temperatures of 300 K and 250 K. If the refrigerator requires 150 J of work input, calculate the amount of heat extracted from the cold reservoir.
  15. A gas undergoes a reversible isothermal compression at a constant temperature of 500 K. If the gas does 300 J of work during this process, calculate the amount of heat released by the gas.
