An endothermic reaction is one that takes heat from its surroundings to increase the delta H or energy level. it causes the surroundings to lower in temperature as it absorbs heat from the surroundings e.g cooling packs. the change in state depends on what reaction is taking place,
e.g melting ice cubes - solid to liquid
boiling water - liquid to gas
(they both absorb heat to occur)
What else can I help you with?
Is butter melted in a pan a endothermic or exothermic change?
Melting butter in a pan is an endothermic process. It requires energy input to break the bonds of the solid butter and convert it into a liquid state.
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
What type of phase change does a substance absorb energy from its surroundings?
When a substance absorbs energy from its surroundings, it undergoes a phase change known as endothermic. This results in an increase in the substance's internal energy, allowing it to transition from one state to another (e.g., from solid to liquid or from liquid to gas) by absorbing heat from its surroundings.
A change of state where energy is given off?
This process is called exothermic reaction, where energy is released in the form of heat. It typically involves a change from a higher energy state to a lower energy state, resulting in the release of energy to the surroundings. An example would be the solidification of molten lava into solid rock, releasing heat energy in the process.
Is the melting of candle wax and exothermic or endothermic change?
The answer is endothermic. The wax is absorbing heat energy, not producing it, and changing from a solid state to a liquid state. If the reactants require more energy than than they are putting out during the reaction, it is said to be endothermic (absorbing of heat). If the reactants give off heat of their own (self sustaining), then it is an exothermic reaction. There are components in some types of wax that will burn, in which case that is an example of an exothermic reaction, but most wax will stop once the heat source is removed.
A change of state reaction that absorbs energy is endothermic?
yes it is endothermic
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.
A change of state reaction of what Energy is endothermic?
absorbed
A change in matter in which energy is taken in is an endothermic change?
Endothermic changes are processes where energy is absorbed by the system from its surroundings. This results in a decrease in temperature in the surroundings during the process. Examples include melting ice and evaporating water.
Is butter melted in a pan a endothermic or exothermic change?
Melting butter in a pan is an endothermic process. It requires energy input to break the bonds of the solid butter and convert it into a liquid state.
Is sublimation exothermic or endothermic?
Sublimation is an endothermic phase transition from solid to gaseous state.
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
What is it called when energy is gained by something during a change of state?
The process of gaining energy during a change of state is known as endothermic phase transition. This occurs when energy is absorbed by a substance, causing it to transition from one state to another, such as from solid to liquid or liquid to gas.
Which change of phase is endothermic?
is Absorbs If you are asking if a change of state is why a reaction may be endothermic, is not always true. It simply depends on what the change of state is to and what it is from, ex: a change from liquid to solid is usually exothermic because it losses energy as the particles slow down and draw near to eachother... and the opposite occurs from solid to liquid (or liquid to gas).
What are endothermic changes of state?
Endothermic changes of state refer to processes in which a substance absorbs heat energy from its surroundings, resulting in a change from a lower energy state to a higher energy state. Common examples include melting (solid to liquid), vaporization (liquid to gas), and sublimation (solid to gas). During these transformations, the temperature of the substance may remain constant until the phase change is complete, as the absorbed energy is used to overcome intermolecular forces.
What type of phase change does a substance absorb energy from its surroundings?
When a substance absorbs energy from its surroundings, it undergoes a phase change known as endothermic. This results in an increase in the substance's internal energy, allowing it to transition from one state to another (e.g., from solid to liquid or from liquid to gas) by absorbing heat from its surroundings.
What do understand by glass transition temperature. Explain whether it is exothermic or endothermic?
glass transition is a change in state. when the state changes from crystalline or rather glassy to a rubbery like state. it should be noted that it is not melting. it is a state change and not a phase change. it is endothermic phenomena because heat is given to a system so that glass transition occurs. because no heat is released during the process it can not be considered to be endothermic.
