An ideal gas expands isothermally, performing 4.80×103 J of work in the process.

Part A

Calculate the change in internal energy of the gas.

Part B

Calculate the heat absorbed during this expansion.

(a)

For an isothermal process, temperature is constant.

Isothermal process: $\"\"$ .

(b)

Work done $\"\"$

According to the first law of thermodynamics: $\"\"$ .

Isothermal process: $\"\"$ .

$\"\"$

Heat absorbed during this expansion is $\"\"$
