What else can I help you with?
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 happen to the temperature during phase change?
The temperature remain constant.
What happen to energy during a change of state Why is it a physical change?
Its released or adsorbed. Its "physical" because no new substance(s) is produced.
What Three Things can happen when a Chemical Reaction occur?
A chemical reaction can change a substance into a solid, liquid, or gas. It may cause a substance to explode or could cause no change at all.
What happen in terms of kinetic theory when you heat a substance?
When you heat a substance, its kinetic energy increases, causing the particles to move faster and further apart. This leads to an increase in the substance's temperature and potentially a change in state, such as melting or boiling.
What will happen if the ignition temperature is lower than the room temperature?
If the ignition temperature is lower than the room temperature, the substance will not ignite or burn spontaneously at room temperature. Ignition temperature refers to the minimum temperature required for a substance to ignite and sustain combustion, so if it is lower than the room temperature, the substance will remain stable at that temperature.
What will happen if you heat a solid substance?
Heating a solid substance usually increases the kinetic energy of its particles, causing them to vibrate and move more rapidly. As a result, the substance may change state, melt into a liquid, or undergo a chemical reaction if it reaches its melting or reaction temperature.
How does temperature happen?
Temperature is a measure of the kinetic energy of the particles in a substance. Temperature in Kelvin is proportional to kinetic energy of particles. Heat on the other hand depends on the amount of substance present.
When temperature and pressure change what can happen to the minerals and rocks?
They can change into coal
Is it possable to add heat but not change the temperature of somthing?
Yes, it is possible to add heat to something without changing its temperature. This can happen during a phase change, such as when melting a solid into a liquid or evaporating a liquid into a gas, where the added heat provides the energy needed for the molecules to change their arrangement without a change in temperature.
What happen to the temperature when ice is heated?
During a phase change (from solid to liquid, as in melting and also from liquid to gas as in boiling) the temperature remains constant, as all of the energy is going to affecting the change, rather than raising the temperature. Once it has changed from solid to liquid, the liquid can then raise in temperature.
Predict what will happen to the state of the substance the atomi and molicular activity?
As the substance undergoes an increase in temperature, its atomic and molecular activity will also increase. This will result in the particles moving faster and having more energy, potentially leading to a change in state if the substance reaches its melting or boiling point.
