The temperature decreases as the gas (vapour) turns back into a liquid. For instance, the hot water vapour from a kettle can be cooled so as to condense back into water.
When a solid changes to a gas (sublimation), it absorbs energy from its surroundings, leading to a decrease in temperature. The energy is used to break the intermolecular forces holding the solid together, rather than raising the temperature.
Increasing the pressure decreases the volume of gas bubbles and does not increase the rate of dissolving a solid in water.
When a substance melts, it changes from a solid to a liquid state, causing an increase in flexibility and a decrease in density. This process also typically involves an increase in temperature. On the other hand, when a substance freezes, it changes from a liquid to a solid state, resulting in a decrease in flexibility and an increase in density. This process usually involves a decrease in temperature.
The graph that best represents a change of phase from a gas to a solid would show a decrease in temperature over time as the gas loses energy and transitions into a solid state. The temperature remains constant during the phase change itself due to the energy being used to break intermolecular bonds rather than increase temperature.
Yes, temperature can affect the rate of neutralization of a solute. Generally, an increase in temperature will increase the rate of reaction for neutralization reactions, while a decrease in temperature will slow down the reaction. However, the extent of this effect depends on the specific solute and reaction conditions.

An increase in temperature typically causes matter to change from a solid to a liquid or from a liquid to a gas. A decrease in temperature often results in the opposite transition, causing matter to change from a gas to a liquid or from a liquid to a solid.
the solid must reach its melting point which varies with every substance

Mass of any chemical, in Chemistry, is always constant, no matter how much you change the conditions.
any increase in temperature will cause gas to occupy a larger volume, any decrease will shrink the volume to a point it becomes liquid. further decrease will cause a solid to form. at -273 degrees celsius everything is solid
You increase the surface area
Temperature is closely linked up to volume. In a solid the species are closely packed. As temperature increase so does the molecular vibrations. At a critical temperature the vibrational energy is sufficiently high that the species break their packing and thus melt into a liquid.
Decreasing temperature would not increase the rate at which a solid dissolves
The movement of particles decrease as temperature decreases, and vice versa. Therefore, they will decrease while freezing.
To change the phase of matter of a substance, you could increase or decrease its temperature or pressure. For example, heating a solid can supply enough energy for it to melt into a liquid, while lowering the temperature of a gas can cause it to condense into a liquid. Similarly, increasing pressure on a gas can lead to its transformation into a liquid or solid. These changes are governed by the principles of thermodynamics and phase diagrams.
