Endothermic is the gaining of internal heat from the sun or hot objects cold blooded animals use this and im pretty sure that there is no word for gas to a solid im pretty sure that is physically impossible

Is the sublimation of carbon dioxide exothermic?
sublimation doesnt nessicarily have anything to do w/ temperature. it is observed in substances such as CO2 (Carbon Dioxide) which have high vapor pressure and low intermolecular force. i take no responsibility for any harm done to u or whoever tests this in some krazy way reading my response to this question....
What is called when you turn a gas into a solid and a solid into a gas?
Turning a solid to a gas is sublimation. You cannot go directly from a gas to a solid. First you have to condense the gas and then freeze it. Sure you can - at the triple point
When solid kbr is dissolved in water the solution gets colder is this endothermic or exothermic?
endothermic.
When solid lead chloride dissolves in hot water is this endothermic or exothermic?
That would be an endothermic process.
What happen during sublimation?
A solid becomes a gas without passing through the stage of being a liquid. It requires energy (endothermic), as the molecules need to move around more quickly and freely. you really only have to write a solid - liquid
What are 2 phase changes that are endothermic or absorbing energy?
Solid to liquid (melting). Liquid to gas (vaporization). Solid to gas/ vapor (sublimation). That's three endothermic changes. :)
Is heat taken away or added in sublimation?
Sublimation is an endothermic physical change (heat is needed).
Is solid to gas endo or exo?
Heat is required to solid for melting and to liquid for evaporation so these are endothermic processes.
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.
Is burning gasoline an exothermic process or an endothermic process?
Solid to gas (sublimation) is endothermic (takes in heat).In other words:A phase change from the solid state to the gas state is endothermic.Sublimation is endothermic (takes in energy).Heat energy must be provided to make it work.When there is a change of state from a solid to a liquid, a solid to a gas, or a liquid to a gas, at a constant temperature, the process is endothermic NOT exothermic. It requires energy to break the intermolecular forces that keep the molecules together, and that reduces the temperature - heat is taken in.
Which phase changes are endothermic?
Based on chemical properties exothermic phase changes are those that release energy. The exothermic phase changes are gas--> liquid, liquid --> solid, and gas--> solid. Looking at a phase diagram if you are going up the "stairs" the conversions require energy going down the "stairs" energy is released.
What are the 3 phases of energy metabolism?
Glycolysis , krebs cycle and electron transport
Is sublimation exothermic or endothermic?
Sublimation is an endothermic phase transition from solid to gaseous state.
What is happening to energy in sublimation?
Sublimation is an endothermic phase transition.Sublimation is the transformation of a solid in a gas, directly, and need energy for this.
Is solid exothermic or endothermic?
A solid is itself neither endothermic or exothermic. However the phase change from liquid to solid will likely be exothermic.

What is it called when a liquid reacts with a solid the temperature dropped and a gas is released?
An endothermic reaction usually exhibits a drop in temperature.
