Endothermic & Exothermic
This type of reaction absorbs heat from its surroundings, causing the temperature to drop.
What is an endothermic reaction?
The study of heat and energy changes in chemical reactions is known as this.
What is thermochemistry?
The ability to do work or cause change is called this.
What is energy?
This type of energy is stored in the bonds of molecules and released during chemical reactions.
What is chemical energy?
This reaction happens when you strike a match, producing heat and light.
What is combustion?
A burning candle is an example of this type of reaction.
What is an exothermic reaction?
The measure of the average kinetic energy of particles in a substance is called this.
What is temperature?
This type of energy is stored due to an object's position or condition.
What is potential energy?
The process in which substances react to form new substances, often releasing or absorbing energy.
What is a chemical reaction?
This gas is produced when you mix vinegar and baking soda.
What is carbon dioxide
This phase change, where a solid turns into a liquid, requires heat energy to occur.
What is melting?
The total energy contained in a system, including both potential and kinetic energy, is called this.
What is internal energy?
The energy of motion is known as this.
What is kinetic energy?
This common exothermic reaction involves a fuel combining with oxygen to release heat and light.
What is combustion?
This type of reaction occurs when iron is exposed to oxygen and water over time.
What is rusting (oxidation)?
This scientific term describes the amount of heat energy released or absorbed during a chemical reaction.
What is enthalpy?
This term, represented by ΔH, tells us if a reaction absorbs or releases heat.
What is enthalpy?
The law that states energy cannot be created or destroyed, only transferred or converted, is called this
What is the Law of Conservation of Energy?
The stored chemical energy in food is converted into this type of energy when you move.
What is kinetic energy?
This process allows plants to convert sunlight into stored chemical energy.
What is photosynthesis?
Photosynthesis is an example of this type of reaction because it requires energy from sunlight
What is an endothermic reaction?
The First Law of Thermodynamics states that energy can neither be created nor destroyed, only this.
What is transferred or converted?
The type of energy stored in chemical bonds, such as in food or fuel.
What is chemical energy?
The energy released or absorbed in a chemical reaction is measured in this unit.
What is a joule (J)?
This reaction in your muscles helps create energy when oxygen levels are low, sometimes causing soreness.
What is lactic acid fermentation?
