The addition of heat or reduction in pressure can cause a substance to change from either a solid (sublimation) or liquid (evaporation) into a gas.
What else can I help you with?
Which process causes a substance in the liquid state to change to a gas?
evaporation
Sensible heat involves a change in a substance's?
Sensible heat involves a change in a substance's temperature without a change in its phase. It is the heat exchange that causes a change in the temperature of a substance but does not result in a change of state (solid, liquid, gas).
Heat energy can change a liquid to a gas during a process called?
The process of heat causing a liquid to change to a gas is called evaporation. The heat increases the speed of the particles within the substance, making them expand and diverge. Once this occurs, the increased energy within the particles causes the substance to change stages into a gas.
What causes a substance to change a phase?
change in temperature
What is the phase change in which substance change form a gas to aliquid?
The phase change in which a substance changes from a gas to a liquid is called condensation. It occurs when the temperature of the gas decreases to reach its condensation point, causing the gas molecules to come together and form a liquid.
What is the name of the energy needed to change a substance from a liquid to a gas?
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
What property of a substance does not change when it turns into gas?
The chemical identity of a substance remains the same when it turns into a gas. The type of atoms and their arrangement within the substance do not change during the phase transition from liquid to gas.
How does increasing the heat energy of a substance change the behavior of particles of the substance?
Increasing the heat energy of a substance causes the particles to move faster and have more kinetic energy. This can lead to an increase in the substance's temperature, change in state (solid to liquid to gas), or possibly result in chemical reactions depending on the substance.
Is forms of gas when heated a physical or chemical property?
The formation of gas when a substance is heated is generally considered a physical change, as it often involves a change in state (like from liquid to gas) without altering the substance's chemical composition. However, if the heating causes a chemical reaction that produces gas (like combustion), it is a chemical change. Thus, whether it is a physical or chemical property depends on the context of the reaction.
What type of change such as burning or rusting causes a substance change?
chemical change
Which is the phase change in which a substance change from a gas to liquid?
It is condensation.
What causes a change in state?
A change in state can be caused by either adding or removing energy from a substance. For example, adding heat can cause a solid to melt into a liquid, and removing heat can cause a liquid to freeze into a solid. Pressure changes can also cause a substance to change state, such as turning a gas into a liquid by increasing pressure.
