If the temperature of 500 mL of air increases from

27\,^\circ C{\mkern 1mu} {\mkern 1mu} \,\,\mathrm{to}{\mkern 1mu} \,{\mkern 1mu} 42\,^\circ C

under constant pressure, then the increase in volume shall be

View answer and explanation

Correct option: C

25\mathrm{ }\,\,mL

Option C (

25\mathrm{ }\,\,mL

) is correct because it is calculated using Charles's Law, which relates volume and temperature at constant pressure.
