A fixed mass of ideal gas is taken from state A to state C in two steps:
1. A→B: volume remains constant while pressure doubles.
2. B→C: pressure remains constant (at its new value) while volume triples.
If the initial temperature is TA, which of the following gives the final temperature TC in terms of TA?
a) TC=3TA
b) TC=2TA
c) TC=6TA
d) TC=5TA
