What else can I help you with?
The behavior of a substance during a phase change?
neither ansorbs nor releases energy
What are properties describes how a substance interact with other substance?
The property that involves how a substance interacts with other substances is known as chemical property. This is what will cause chemical changes during reactions.
What is a characteristic that best describes what happens during a physical change?
A physical change involves a transformation in the appearance, shape, or state of a substance, while its chemical composition remains the same. This means that no new substances are formed during a physical change.
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 best describes the enthalpy of formation of a substance?
The energy change that happens when a substance forms from its elements (APEX)
Which best describes the narrators behavior during the story?
Paranoid, looking for a way out
What describes testing a substance for flammability?
Testing a substance for flammability involves exposing it to a heat source or flame to observe if it ignites and how it burns. The test helps determine the propensity of a substance to catch fire and how it behaves when it does. Results categorize substances as non-flammable, flammable, or highly flammable based on their behavior during the test.
How does the energy of a substance change during an exothermic change?
During an exothermic change, energy is released from the substance in the form of heat to the surroundings. This results in a decrease in the internal energy of the substance, leading to a decrease in its temperature.
A change during which the basic composition of the substance is not altered is?
Physical Change
What do you think will happen to the temperature of a substance during a phase change?
During a phase change, the temperature of a substance remains constant. This is because the energy being absorbed or released is used to break or form intermolecular bonds, rather than to change the temperature of the substance.
What doesnt change during the composition of a substance?
The composition of a chemical compound is not changed during a physical change.
Does the energy content of a substance change during a phase change?
Yes, but not the temperature.
