Question

We know that in isothermal process ΔT=0 which implies Q=W. My doubt is that Q also equals nCΔT and ΔT=0 due to which Q should be equal to zero and W as well.please resolve my confusion

Solution

As we know work is
W=integral P times d V so in isothermal process if we keep temperature constant there will be change in volume and pressure.
PV=nRT T constant so
​​​​ PV = constant so when we draw this equation we can see that it is a hyperbolic graph and it has area under the curve means it is a bounded function.so there is some work done.so work done can't be zero.and the formula of Q= nc∆T is not working for all thermodynamics process it has some limitations.but the internal energy always depends on temperature.
hope this helps:)
