<span>No. of moles of ammonia: 11.4/(14+3) = 0.671mol
molality of solution: 0.671/0.2 = 3.35mol/kg
Change in temp: Kb x molality = 0.52x 3.35=1.74

Hope this helps :)

A chemist heats a gas within a sealed, rigid container. Which statement describes the changes that occur in the gas? (1 point)
Assoli18 [71]

When a gas is heated in a sealed container, the gas particles move faster and hit the sides of the container with more force leading to an increase in the pressure of the gas.

An increase in the temperature of a gas increases the collision rate of the molecules of the gas according to the kinetic theory.

With increased kinetic energy, the molecules of the gases collide more frequently with each other and the walls of the container.

The collision creates an increase in the magnitude of pressure inside the container.
