Problem $04\mathrm{.}135-$ Energy balance for an ideal gas in a piston$-$cylinder device

A vertical $\backslash (25\mathrm{.}00-\backslash$mathrm$\{$cm$\}\backslash )-$diameter pistoncylinder device contains an ideal gas at the ambient conditions of $1$ bar and $\backslash (24^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ).$ Initially, the inner face of the piston is $20$ cm from the base of the cylinder. Now an external shaft connected to the piston exerts a force corresponding to a boundary work input of $0\mathrm{.}1$ kJ $.$ The temperature of the gas remains constant during the process.

Problem $04\mathrm{.}135.$a $-$ Find heat transfer

Determine the amount of heat transfer. $($Round the final answer to one decimal places.$)($Include a minus sign if necessary.$)$

The amount of heat transfer is
