Electrolysis of water to oxygen and hydrogen gas
What else can I help you with?
What is the difference between ectothermic and endothermic?
endothermic is when something changes from to hot to cold and ectothermic is when something changes from cold to hot.
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
What contrast endothermic and exothermic changes?
Exothermic: release of heat Endothermic: absorption of heat
Which of the changes boiling freezing and condensation is endothermic?
For boiling energy is needed, so it's endothermic.
What are the phase changes that are endothermic?
For example melting or boiling.
What is the relationship between endothermic reactions and temperature changes?
Endothermic reactions absorb heat from their surroundings, causing a decrease in temperature.
What are the three phase changes?
The 3 types of endothermic phase changes are the movement from solid to liquid, the movement from liquid to gas, and the movement form gas to plasma. Endothermic is the absorbing of heat.
What are 2 phase changes that are endothermic or absorbing energy?
Two phase changes that are endothermic or absorbing energy are melting (solid to liquid) and vaporization (liquid to gas). During these phase changes, energy is absorbed to break the intermolecular forces holding the particles together, allowing them to move more freely in their new state.
Where does the thermal energy go in such endothermic phase changes?
It is converted to bond energy
What is the thermochemical equation for endothermic changes?
A + B + Heat → C, ΔH > 0
Water changes phases when heat is added or subtracted?
Boiling and melting are endothermic. Freezing is exothermic.
How can you tell the difference between an endothermic and exothermic reaction?
You can generally tell by changes in temperature, whether you have an exothermic reaction which produces heat, or an endothermic reaction which consumes heat.
