Air is used in a Carnot engine where the volumes at the beginning of the constant temperature heat addition and end of the constant temperature heat rejection are 0.356 cm3 and 5.573 cm³ respectively. Calculate the thermal efficiency. O 0.713 0.667 0.642 O 0.75

An ideal gas expands isothermally, performing 5.00×103 J of work in the process.  Part A Calculate the change in internal energy of the gas. Part B Calculate the heat absorbed during this expansion.

A gas contained in a cylinder fitted with a frictionless piston expands against a constant external pressure of 1atm from a volume of 5L to a volume of 10L. In doing so, it absorbs 400 J of thermal energy from its surroundings. Determine the change in internal energy of system.

The heat engine shown in the figure uses 2.0 mol of a monatomic gas as the working substance. (Figure 1) igure p (kPa) 600- 400 200 0 0 0.025 0.050 V (m³) 1 of 1 Part E part.
