Question

The work is done when a gas is compressed in a cylinder is 402J. During the process, there is a heat transfer of 128J from the gas to the surroundings. Calculate the energy change for this process.​

Answer 1

$\huge{\underline{\mathtt{\red{A}\pink{N}\green{S} \blue{W} \purple{E} \orange{R}}}}:$

$given: q = - 128j \\ w = 402j \\energy \: change = \delta_{E} = ?\\ we \: know \: that = > \\ \delta_{E} = q + w \\ = ( - 128) + 402 \\ = 274 \: joules \\the \:energy \:change\: for \:this\: process\: is \:274 \:joules$
