m 011) 10.) When 1 mol of a gas is heated at constant volume, 16. C temperature is raised from 298 to 308 K. Hcat supplied to the gas is 500 J. Then which statement 1S corect ? (a) q= W= 500 J, AU = 0 S d) Mb) q= AU=500 J, W=0 d Qud (c) q= W= 500J, AU = W= 0 do Fdg (d) AU= 0, q = W=- 500 J Which one of the following equations does not corectly represent the first law of thermodynamics for the given process ? (a) isothermal process: q =- W (b) cyclic process:q=-w (c) isochoric process : AE ==q (d) adiabatic process: AE =- w (e) expansion of a gas into vacuum: AE=g 11 17 18.
