Which of the following must be true about an ideal gas that undergoes an isothermal expansion? (there may be more than one correct choice.)
(a) no heat enters the gas.
(b) the pressure of the gas decreases.
(c) the internal energy of the gas does not change.
(d) the gas does positive work.
(65°f − 32) × 5/9 = 18.333°c
correct answer is which is not any option
in this question we have given,
force on piston 1,=6600n
area of piston 1,=
force on piston 2,=9900n
we have to find area of piston 2, =?
according to pascal's law, the pressure is transmitted with equal intensity to every part of the fluid:
in equation 1
