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)
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.
Which best describes the narrators behavior during the story?
Paranoid, looking for a way out
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.
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.
A change during which the basic composition of the substance is not altered is?
Physical Change
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.
