Is boiling an egg endothermic or exothermic?
It is endothermic as the water mus gain energy to go from a liquid to a gas.
Is boiling a exothermic?
Boiling is not an exothermic process; it is an endothermic process. During boiling, a substance absorbs heat energy from its surroundings to convert from a liquid to a gas. This absorption of energy is necessary to overcome intermolecular forces, allowing the molecules to escape into the vapor phase. As a result, boiling requires heat input rather than releasing it.
What is boiling and melting and condensation best described as?
The three of boiling, melting, and condensation describe matter change of state.Boiling is sate change from liquid to gasmelting is state change from solid to liquidcondensation is state change from gas to liquid
What are two examples of changes in state that will generate an increase in molecular motion?
Melting ice to form liquid water or boiling liquid water to produce steam are two examples of changes in state that lead to an increase in molecular motion. In both cases, the added energy causes the molecules to move more rapidly and with greater freedom.
When a substance melts or boil it absorbs what?
When a substance melts or boils, it absorbs heat energy from the surroundings in order to overcome the intermolecular forces holding its particles together. This energy is used to break these forces and allow the particles to move more freely, transitioning from a solid to a liquid (melting) or from a liquid to a gas (boiling).
What rapidly changes to a gas when it absorbs enough energy to reach the boiling point?
Liquid does this.
Which of the changes boiling freezing and condensation is endothermic?
For boiling energy is needed, so it's endothermic.
Why does compressed air changes to vapour?
Compressed air changes to vapor when it is heated past its boiling point, causing it to transition from a gaseous state to a vapor state. This process is known as vaporization or evaporation, where the substance absorbs heat energy and transforms into its gaseous form.
Is boiling an egg endothermic or exothermic?
It is endothermic as the water mus gain energy to go from a liquid to a gas.
When most substances are heated they....?
They expand
The change in which ice absorbs energy and melts is?
An endothermic change; or a change of state. Endothermic because it absorbs energy. Change of state because ti changes from a solid to a liquid.
What happens to the particles in an object when it absorbs radiant energy?
When an object absorbs radiant energy, its particles absorb the energy and start to vibrate or move more rapidly. This increased motion can cause the temperature of the object to rise, leading to an increase in kinetic energy of its particles.
What is it called when something changes from a liquid to a gas?
When a substance changes from a liquid to a gas, it is called vaporization or evaporation. This process occurs when the substance absorbs enough energy to overcome the forces holding its molecules together in the liquid phase.
Is it true or false that a gas absorbs energy as it changes into a liquid?
True, when a gas changes into a liquid, it releases energy, typically in the form of heat. This process is called condensation.
Is boiling a exothermic?
Boiling is not an exothermic process; it is an endothermic process. During boiling, a substance absorbs heat energy from its surroundings to convert from a liquid to a gas. This absorption of energy is necessary to overcome intermolecular forces, allowing the molecules to escape into the vapor phase. As a result, boiling requires heat input rather than releasing it.
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.
Water changes phases when heat is added or subtracted?
Boiling and melting are endothermic. Freezing is exothermic.
