Alguien me puede ayudarme con este problema? Porfa: Durante un proceso adiabático la energía interna
de un gas ideal disminuye en 30 kJ. Luego el gas
se expande isotérmicamente desarrollando una
cantidad de trabajo que es numéricamente igual
al doble de trabajo del primer proceso.
Determine la cantidad de calor en este segundo
proceso.
A) 15 kJ B) 30 kJ C) 50 kJ
D) 60 kJ E) 90 kJ

8. why do radio telescopes convert radio waves (analog signals) to electrical (digital) signals for analysis? (hint: what did the article say about the advantages of digital signals? )

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
