(d) Si el elevador tiene una masa de 1,650 kg y una aceleración hacia arriba de 2.5 m/s2. Encuentre T (en N).

Using the ideal gas law we can determine this:

PV = nRT

n and R are constants but V and T are doubled:

that is the same as multiplying the entire equation by 2:

2(PV) = 2(nRT)

Therefore if we distribute we can get what is wanted:

P*2V = n*R*2T

Which then shows that pressure would stay constant if temperature and volume were to both double.
