A change in matter in which energy is taken in is an endothermic change?
Its where heat is taken in in a reaction eg making a cake is an endothermic reaction as heat is taken in to start it ;)
How much energy is taken to change water into a solid?
The same amount of energy that is required to change it from a solid to a liquid. About 334.0 kJ/kg.
Can energy change to one anothere?
Yes, for instance potential energy can change into kientic energy and electromagnetic raditaion energy can change into thermal or chemical energy. It is also possible to change matter into energy and energy into matter.
Sample problem of power?
(Air and rolling resistance ignored)Power required = energy change / time taken>Problem:Power required to accelerate 1000 kg car from 0 to 60 mph ( 26.82 metres / second) in 3 seconds ?>kinetic energy gained (energy change)= 0.5 * mass * velocity2,>so 0.5 * 1000 * 26.822 = 359656.2 joules>Power required = energy change / time taken= 359656.2 / 3= 119885.4 joules / second (watts)= 119.8854 kw (about 161 bhp)
How can mechanical energy change into chemical energy?
when your moving water what does mechanical energy change to
endothermic?
A reaction where energy is taken in.
What is the Change in which energy is taken in?
endothermic change
What is the change of energy taken in?
endothermic change
Is a change in matter in which energy is taken as an endothermic change?
yes
Can energy be taken during a physical change?
no
What energy changes occur when a photograph is taken?
As per my knowledge, when a photograph is taken there is a complex change of CHEMICAL energy to LIGHT energy ..... (Hope this helps you..)
A change in matter in which energy is taken in is an endothermic change?
Its where heat is taken in in a reaction eg making a cake is an endothermic reaction as heat is taken in to start it ;)
What must be added or taken away in order for matter to changes states?
Energy must be added or taken away.
What is different between exothermic and endothermic reactions?
If energy is released as a result of a process, an exothermic change has taken place. If a constant input of energy is required to drive a physical or chemical change, the change is described as endothermic.
Is energy taken in an exothermic change?
no, endothermic trust me it shows it in my book
What is the difference between endothemic and exothemic?
The difference is that the endothemic change is when energy is absorbed from the substance and exothermic change is when energy is removed or taken out of the substance.
How much energy is taken to change water into a solid?
The same amount of energy that is required to change it from a solid to a liquid. About 334.0 kJ/kg.
