When the volume of a gas decreases at constant temperature, what will happen to pressure?
pressure increases due to increased kinetic energy of each gas particle
pressure increases due to the smaller volume and more collisions with the sides of the container
molecules collide less due to the pressure decrease due to smaller volume of molecules
pressure increases because molecules are moving faster due to the increase number of molecules

MULTIPLE CHOICE QUESTION

An ionic crystal is added to water and starts to dissolve as shown in the particulate representation above. Based on the orientation of the water molecules, what can be assumed about the charge of the hydrated particle indicated by the arrow?
The particle is positively charged, because the oxygen atoms in water are attracted to it.
The particle is negatively charged, because hydrogen atoms in water are attracted to it.
The particle is both positively and negatively charged, because the water molecules are attracted to it.
The particle is neutral, because the dipoles of the water molecules neutralize the charge of the particle.
Answer explanation
The oxygen atom of a water molecule has a partial negative charge due to oxygen’s greater electronegativity compared to hydrogen. The negative oxygen in H2O is attracted to positive particles (e.g., cations). The diagram shows the oxygen atoms of water molecules next to the particle indicated by the arrow, indicating that it has a positive charge.
