How can I calculate thermochemistry equations for phase changes?

Phase changes represent the transformation of a thermodynamic system from one state of matter to another by way of heat transfer. A state of matter (or phase) is described as having uniform physical properties; during phase changes, certain properties change. Now, heating stuff up takes energy; for a pure substance in a single phase, this energy can be

changes of state between solids, liquids and gases

This page looks at what happens to the particles in solids, liquids and gases during changes of state.

For instance, water vapor can condense into liquid water, and liquid water can freeze into ice. The process is cyclical and allows matter to transition between different states depending on the conditions, such as temperature and pressure. potentially changing a solid into a liquid or a liquid into a gas. At the phase transition point, such

10.3: Phase Transitions

Therefore, we define the normal boiling point as the temperature at which a liquid changes to a gas when the surrounding pressure is exactly 1 atm, or 760 torr. Unless otherwise specified, it is assumed that a boiling point is for 1 atm of pressure. Like the solid/liquid phase change, the liquid/gas phase change involves energy.

Latent Heat Calculator

This process of turning water into vapor takes some energy. This is the latent heat. Once all the water is turned into vapor, a further transfer of heat will simply increase the temperature again. A change from a liquid to a gaseous phase is an example of a phase transition. Another common phase transition is from a solid to a liquid phase.

Specific Heat Calculator

Find the initial and final temperature as well as the mass of the sample and energy supplied. Subtract the final and initial temperature to get the change in temperature (ΔT). Multiply the change in temperature with the mass of the sample. Divide the heat supplied/energy with the product. The formula is C = Q / (ΔT × m).

10.3 Phase Transitions

The temperature at which the solid and liquid phases of a given substance are in equilibrium is called the melting point of the solid or the freezing point of the liquid. Use of one term or the other is normally dictated by the direction of the phase transition being considered, for example, solid to liquid (melting) or liquid to solid (freezing).

The Changing States of Solids, Liquids, and Gases

During changes of state (phase changes), the temperature remains constant even though the liquid contains more energy than the ice (because the particles in liquids move faster than the particles in solids). Boiling point of water If you heat a pot of cool water, the temperature of the water rises and the particles move faster and faster as

1.6: Phase Changes

Phase transitions play an important theoretical and practical role in the study of heat flow. In melting (or "fusion"), a solid turns into a liquid; the opposite process is freezing evaporation, a liquid turns into a gas; the opposite process is condensation. A substance melts or freezes at a temperature called its melting point, and boils (evaporates rapidly) or condenses at its

All energy added to the system at this stage is used to convert solid ice into liquid water. Image Credits: By Cawang via Wikimedia Commons. This macroscopic behavior demonstrates quite clearly that energy must be supplied to a solid in order to melt it. On a microscopic level melting involves separating molecules which attract each other.

1.9: Heat and changes in physical states of matter

If heat is removed from a substance at its melting point, the reverse of melting, i.e., freezing, happens, i.e., the liquid gradually changes from liquid to solid phase. The energy equal to the heat of fusion is released during the freezing process. Fig. 1.9.2 shows ice and water at 0 o C –an example of melting and freezing.

What happens in a change of State from liquid to solid?

In the change of state from liquid to solid energy is given off. The energy given off by this transition is the same amount as the energy required to freeze the matter. A very common phase change is between liquid and gases. This change of state is referred to as vaporization/boiling (liquid to gas) or condensation (gas to liquid).

What is the energy given off by a phase change?

The energy given off by this transition is the same amount as the energy required to freeze the matter. A very common phase change is between liquid and gases. This change of state is referred to as vaporization/boiling (liquid to gas) or condensation (gas to liquid). So what is going on a microscopic level?

What happens when a gas phase changes to a liquid?

The change from the gas phase to the liquid is called condensation. When the rate of condensation becomes equal to the rate of vaporization, neither the amount of the liquid nor the amount of the vapor in the container changes. The vapor in the container is then said to be in equilibrium with the liquid.
