By supplying energy to it.
Explanation:
Since an endothermic reaction, by definition, NEEDS energy to go on, it will cool down (= taking heat energy from the reactants). It will stop itself as any reaction will slow down at lower(ing) temperatures.
So SUPPLY of heat is at least necessary to KEEP temperature at its minimum level of 'ongoing' reaction. (to: Chasity cordero)
In an endothermic chemical change, heat flows into the reaction (as opposed to exothermic reactions where the reaction gives off heat). To initiate the reaction only requires bringing the reactants into contact, but if it is too cold, the reaction will only proceed slowly. To accelerate the reaction and keep it going, there must be a constant supply of heat to the reactants. It is also necessary to constantly supply fresh reactants and preferably remove the reaction products - otherwise the reaction will approach thermodynamic equilibrium and essentially cease.
By heat , the more you add the more it keep going on
You add things in it or you can take heat from it' i.e. you have to cool it. this way you can take the reaction forward.
An endothermic reaction needs heat to keep it going … SO, heat the reactants.
You might cause an endothermic chemical change to begin and keep going by: adding thermal energy.
keep adding heat
No. Flattening is a physical change because it does not cause a change in chemical composition.
The Physical change.
When chemical changes it can cause a chemical reaction..it can fizz or explode or sometimes change temperatures..for example baking soda and vinegar fizz..
No. Physical cause it hasn't changed its just gone from wet to dry :-)
Very probable a chemical change; but also physical changes can be the cause.

A chemical change can be caused by a reaction. It an element or compound reacts with another, it is known as a chemical change.

No. Flattening is a physical change because it does not cause a change in chemical composition.
Change in temperature is not a chemical change rather it is a physical change because it does not cause any change in composition or chemical properties of matter.
It is physical change
Cooking food can cause chemical Changes
Yes, it does.
