Question

If 2 moles of helium undergo a temperature increase of 100 K at constant pressure, how much energy has been transferred to the helium as heat

Answer 1

`Q=4154J`

Step-by-step explanation:

Hello,

In this case, the involved heat in this heating process is considered to be computed via:

`Q=nCp\Delta T`

Whereas we assume a constant molar specific heat of helium which is 20.77 J/(mol*K), thus, the transferred energy in the form of heat turns out:

`Q=2mol*20.77(J)/(mol*K) *100K\\\\Q=4154J`
