What else can I help you with?
What is ALWAYS true about the temperature of a substance during a phase change?
During a phase change, the temperature of a substance remains constant despite the addition or removal of heat. This is due to the energy being used to break or form intermolecular bonds rather than increase the kinetic energy of the particles.
What is true for a substance that absorbs energy?
When a substance absorbs energy, its internal energy increases, which can lead to a rise in temperature, a change in phase (e.g., from solid to liquid), or chemical reactions. Absorbing energy typically causes the substance's particles to move more quickly or rearrange themselves in a way that stores the additional energy.
What is true about triple point?
The triple point is the temperature and pressure at which a substance can exist in equilibrium as a solid, liquid, and gas simultaneously. It is a unique point on a substance's phase diagram where all three phases coexist. The triple point is a characteristic property of a substance.
True or False Sublimation is a change from solid to gas?
Yes, sublimation is a change from solid to gas.
When a substance loses or absorbs energy its temperature can change true or false?
True. When a substance loses energy, its temperature can decrease, while when it absorbs energy, its temperature can increase. This is because energy is transferred as heat, which can lead to changes in temperature.
True or false the temperature of a substance changes during a change in state?
False. The temperature of a substance remains constant during a change in state until all of the substance has completed the phase change.
True or False- The freezing point of a substance is equal to the melting point of a substance?
True. The freezing point of a substance is the temperature at which it changes from a liquid phase to a solid phase, while the melting point is the temperature at which it changes from a solid phase to a liquid phase. In equilibrium, the freezing point and melting point of a substance are the same.
During a chemical change the form of a substance is altered but not its identity true or false?
The statement is false: A chemical change of a substance is defined as a change in which the substance is not the same substance after the change as it was before.
Is The phase of any substance is dependent upon temperature and pressure true or false?
do you have homeschool that your asking this because i do and im looking for the same answer
Is it true melting is considered an sublimation change because energy is gained by substance as it changes stae?
Melting is a phase change in which a substance changes from the solid state to the liquid state. Sublimation is a phase change in which a solid moves directly into the gas phase. Both melting and sublimation are two types of physical change.
True or false When frozen water melts it is undergoing a physical change?
Actually it is undergoing a crappy change.
Is Phase of any substance is dependent upon temperature and pressure?
true
Which may be true for a substance that absorbs energy?
The energy decreases the molecular motion and the kinetic energy of the substance.
Is it true are false that a physical change of a substance changes its chemical makeup?
true
Is it true that the properties of a substance change when it is added to a mixture?
yes.true
What is ALWAYS true about the temperature of a substance during a phase change?
During a phase change, the temperature of a substance remains constant despite the addition or removal of heat. This is due to the energy being used to break or form intermolecular bonds rather than increase the kinetic energy of the particles.
Would it be true to say that solidfication is from a liquid to gas?
False. Solidification when a substance that is in a liquid changes phase to a solid.
