Heat absorbing. An endothermic reaction is one in which heat must be supplied to further the reaction.

A reaction or process that is endothermic takes in heat from the surroundings.

Reactions in which heat flows from the surroundings into the system are called endothermic. Since we observe the "surroundings," endothermic reactions are often detected by noting a decrease in temperature.

A term that describes animals such as mammals and birds that are capable of regulating their body temperature without a heat gradient. Nine tenths of a mammals energy is spent on maintaining a constant temperature, explaining why mammals have a higher metabolism and eat more than reptiles.

a change which takes place with the absorption of heat; a process requiring energy. (see exothermic)

A process in which the system absorbs heat from the surroundings. See exothermic.

is the term given to a reaction which takes in heat energy from its surroundings.

(of a chemical reaction or compound) occurring or formed with absorption of heat

a reaction that requires energy to

a reaction that takes heat in from the environment, that is, heat is absorbed by the system.

This applies to any reaction that absorbs heat.

An animal that produces its own body heat internally; warm blooded.

Reaction that absorbs heat from its surroundings as the reaction proceeds.

Characterized by or causing the absorption of heat. Compare Exothermic.

Pertaining to a chemical reaction which occurs with absorption of heat.

accompanied by absorption/emission of heat

refers to a reaction in which energy (as heat) flows into the system.

Reactions that proceed with absorption of enthalpy (heat energy) are termed endothermic; see exothermic.

A term used to characterize a chemical reaction which requires absorption of heat from an external source.

warm-blooded; being able to produce body heat and maintain a constant temperature

A chemical reaction which allows materials to absorb heat.

Indicating a reaction which absorbs heat.

a characteristic meaning an intake of energy, especially heat

Producing thermoregulatory heat internally.

A reaction that gives off energy. The product is in a lower energy state than the reactants.

A heat absorbing reaction or a reaction that requires heat.

a reaction which absorbs energy (i.e., cools its surroundings), H is positive.

In chemistry, a type of process that absorbs heat from its surroundings.

Chemical reaction that absorbs heat.

Absorbs heat. A process is said to be endothermic when it absorbs heat.

endothermy; endotherm animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. Convergent in birds. animals that generate their own body heat through metabolic processes.

Characterized by or formed with absorption of heat

a process or change that takes place with absorption of heat and requires high temperature for initiation and maintenance

Describes processes that absorb heat energy.

a reaction in which heat is absorbed.

Referring to a process that absorbs energy.

Drawing heat inward, simultaneously cooling the environment around.

Pertaining to heat absorption. A chemical reaction is endothermic if it requires heat to complete the reaction.

A foaming agent's chemistry causing heat to be absorbed when the gas is generated.

A term used to describe a process or change in which heat is absorbed and that requires high temperature for the initiation and maintenance. For example, melting ice absorbs heat and is, therefore, an endothermic process.

Heat absorbing reaction. Produced by a chemical change in which there is an absorption of heat.

A process or reaction that absorbs heat. For example, ice melting is an example of an endothermic process because it absorbs heat from its surroundings.

Having a relatively stable internal body temperature and body heat that is generated internally, by the organism's own metabolism. For example, mammals are endothermic.

Endothermic animals generate their own body heat to maintain their body temperature. Birds and mammals are endothermic.

A process or chemical reaction, which is accompanied by absorption of heat.

capable physiologically of maintaining a contant body temperature, as humans do; ecto thermic species have body temperatures that change with the temperature of their environment ENSO El Niño Southern Oscillation

Having a relatively high and constant body temperature mostly independent of the surroundings. "Warm-blooded".

warm-blooded; maintaining a body temperature largely independent of the environment

Warm blooded animals who cannot regulate their own body temperatures.
