What statement describes the phase change that when dry ice is placed in an open container at room temperature?
sublimation
Why does temperature no change during energy phase change?
During a phase change, the heat transferred to a substance is used to break intermolecular forces (latent heat), and thus the temperature of the substance does not change. The opposite also occurs: heat is transferred from a substance during a phase change without a decrease in temperature as intermolecular bonds form.
A change of phase takes place at a constant?
A change of phase takes place at a constant temperature and pressure. During a change of phase, the substance absorbs or releases latent heat without a change in temperature.
The phase change of water to ice is called?
The phase change of water (liquid) to ice (solid) is called solidification.
What happens to a substances temperature during a phase change?
stays the same
What is a physical change that occurs because of a decrease in temperature?
When the temperature decreases, substances can change phase from a gas to a liquid or from a liquid to a solid. This is known as condensation or freezing.
Freezing is the phase change that occurs when a changes into a?
Freezing is the phase change that occurs when a liquidchanges into a solid.
What phase change occurs as the temperature of the sample at 3 ATM is raised from -90ºC to -50ºC?
This depends on the type of sample.
What statement describes the phase change that when dry ice is placed in an open container at room temperature?
sublimation
Is the change of phase from a liquid to a gas at any temperature?
Each element and compound has its own temperature at which the phase change from liquid to gas (evaporation) occurs. For instance, the evaporation of water occurs at 100oC, whereas the same for (liquid) oxygen is -182.96oC. Some substances sublimate, i.e. that change from solid to gas without going through the liquid state/phase first; e.g. (solid) carbon dioxide.

The opposite also occurs: heat is transferred from a substance during a phase change without a decrease in temperature as intermolecular bonds form.
When matter changes from one state to another what do you call this?
This is called a change in phase or a phase transition. It occurs when a substance transitions from one of the states of matter (solid, liquid, gas) to another due to changes in temperature or pressure.
A change of phase takes place at a constant?
A change of phase takes place at a constant temperature and pressure. During a change of phase, the substance absorbs or releases latent heat without a change in temperature.
Does the temperature of a substance change before the change of state is complete?
No. During a phase change the temperature is constant until the phase change is complete.
How do you get a change of phase?
Change of phase is caused 99% of the time by a change in temperature or pressure.
The phase change of water to ice is called?
The phase change of water (liquid) to ice (solid) is called solidification.
What does a shallow slope say on a phase change graph?
A shallow slope on a phase change graph indicates that a relatively small amount of heat is required to change the temperature of the substance during a phase change, such as melting or boiling. This typically occurs when the substance is undergoing a phase transition, where energy is being used to overcome intermolecular forces rather than increasing temperature. Consequently, the shallow slope reflects a higher specific heat capacity during the phase change.
