Question

During isothermal expansion of an ideal gas, its
(a) internal energy increases
(b) enthalpy decreases
(c) enthalpy remains unaffected
(d) enthalpy reduces to zero.

Answer 1

Explanation:

during an isothermal process,the temperature remains constant. Hence the internal energy of the system remains constant

Answer 2

Answer:

optión c

Explanation:

delta h equals delta u + delta ngrt

delta u= 0

delta t = 0

so delta h= 0
