Primera pregunta : en un experimento que se desarrolla a presión constante , un gas a 275 k ocupa 6 l. construye la gráfica del volumen ocupado por el gas en funcion de la temperatura para valores comprendidos entre 200 a 400 k

segunda pregunta: un gas se encuentra a una temperatura de 298 k ocupa un volumen de 5x10´-3 m´3
_que volumen ocupara si aumentamos su temperatura en 50 k

por favor

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

the answer would be a

wher is the rest of the question
