Which is true of a melting point and a boiling point?
A melting point is the temperature at which a substance changes from a solid to a liquid state, while a boiling point is the temperature at which a substance changes from a liquid to a gas. Both melting and boiling points are characteristic physical properties of a substance and can be used to identify and classify materials.
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.
What effect does the speed of molecules have of matter?
The speed of molecules affects the temperature of a substance. As the speed of molecules increases, the temperature of the substance also increases. This can lead to changes in the physical state of matter, such as melting or boiling.
Is it true or false that the temp. at which a liquid turns to a gas is called the boiling point?
True. The temperature at which a liquid turns into a gas is called the boiling point.
Which of the statements about the triple point is true?
it is a property of substances. it is the temperature and pressure at which all three states of a substance coexist it is easily identified from a phasediagram (apex answer)
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.
Which is true of a melting point and a boiling point?
A melting point is the temperature at which a substance changes from a solid to a liquid state, while a boiling point is the temperature at which a substance changes from a liquid to a gas. Both melting and boiling points are characteristic physical properties of a substance and can be used to identify and classify materials.
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.
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.
What statement is true as you move from ice to water to steam?
Temperature, kinetic energy, and compressibility all increase
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
A trivia question When evaporating a liquid you add heat until the liquid reaches a temperature at which it changes to bubbles of gas below its surface. Is this True or False?
True. When evaporating a liquid, heat is added to increase its temperature until it reaches its boiling point. At this temperature, the liquid changes to bubbles of gas below its surface, transitioning from a liquid to a gas phase.
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- Energy is transferred as heat from a substance at high temperature to a substance at low temperature?
True. Heat is transferred from a substance at high temperature to a substance at low temperature to reach thermal equilibrium.
Do different types of matter melt at different temperatures?
Yes, different types of matter have different melting points. Each substance has a specific temperature at which it changes from a solid to a liquid state. This temperature can vary based on the molecular structure and intermolecular forces of the material.
True or false when ice changes to a liquid it asorbs energy?
true, when ice changes to a liquid it asorbs heat energy .
True or false temperature is a measure of how hot or cold a substance is?
How hot or cold a substance is the temperature, so a thermometer will measure it.
