What is the process called when a substance changes from a solid to a liquid?
The process of a substance changing from a solid to a liquid is called melting. During melting, the solid substance absorbs heat energy, causing its particles to gain enough kinetic energy to break free of their fixed positions in the solid structure and transition into the more disordered liquid state.
What is the process called when a substance changes from a liquid to a gas?
The process is called "vaporization" or "evaporation.
What is the process called when a substance changes from a gas to a liquid?
The process is called condensation.
What is the process called when a substance changes from a liquid to a solid?
The process of a substance changing from a liquid to a solid is called solidification, or more commonly known as freezing.
What is the process called when a substance changes from a solid directly to a gas without becoming a liquid first?
The process is called sublimation. In this process, a solid substance turns directly into a gas without passing through the liquid state.
What is the process called when a substance changes from a gas directly to a solid without becoming a liquid first?
The process is called deposition.
What happens to the temperature of a substance during a melting process?
During the melting process, the temperature of a substance remains constant even as it absorbs heat energy. This is because the heat energy is used to break the bonds between the molecules in the solid state, rather than increasing the temperature of the substance. Once all the solid has melted, the temperature will start to rise again as heat energy is used to increase the kinetic energy of the molecules in the liquid state.
What happens to the temperature of a substance during a boiling process?
During a boiling process, the temperature of a substance remains constant until all the liquid has been converted into vapor. This is because the added heat energy is used to break the intermolecular forces between the molecules, rather than increasing the temperature. Once all the liquid has been converted to vapor, the temperature will start to rise again.
What happens to the temperature of a substance during a condensation process?
During a condensation process, the temperature of a substance decreases. This is because the substance releases heat as it changes from a gas to a liquid state, leading to a reduction in temperature. The heat energy is transferred to the surroundings as the vapor molecules lose kinetic energy and are brought closer together to form a liquid.
What happens to the temperature of a substance during a freezing process?
During the freezing process, the temperature of a substance decreases as its heat energy is gradually removed. As the substance transitions from a liquid to a solid state, the particles within the substance slow down and become more closely packed together, resulting in a decrease in temperature until the substance reaches its freezing point.
