What describes a perpetual motion machine?
A motor that requires no energy input once it is running
What is A reactant in which energy is taken in?
You probably mean "what reaction releases energy," in which case, lots. Reactions that release energy into the environment are called exothermic reactions. An example of which would be mixing sodium (Na) and water (H2O) to form sodium hydroxide (NaOH), hydride (H2), and heat/energy. 2Na + 2H2O ---> 2NaOH + H2 + heat/energy
How much mechanical energy will be provided by a motor that is 70 percent efficient and requires 1960 joules of energy?
Output energy divided by %eff.= input energy %eff. is energy out divided by energy in
When the hydrosphere receives energy from the Sun what does water do A.condenses. B.precipitates. C.evaporates. D. runs off?
The only process which requires the input of energy is evaporation.
Why radar antenna is an example of power amplification?
On its own, it isn't. Amplification requires input of energy - an antenna is entirely passive.
Which of these reactions requires a net input of energy from its surroundings?
Endergonic
What type of reactions are considered uphill?
Anabolic because it requires the input of energy.
Do endergonic reactions release energy?
No they do not. An endergonic reaction requires a net input of energy to force it to occur.
A chemical reaction that requires a net input of energy?
"Activation Energy reactions"; Endothermic reactions require energy.
Photosynthesis requires an input of energy to occur. Which kind of reaction does this describe?
an endothermic reaction
What is the term for the reactions that required energy input?
endothermic reactions
What are observations of indothermic reactions?
I assume you mean endothermic and not indothermic, in which case it means the reaction requires the input of heat energy to make it occur, or it will occur spontaneously, but will cause a reduction in temperature of the reaction mixture or surroundings.
Is it true or false that all chemical reactions require an initial input of energy called catalysis?
FalseAll chemical reactions require an initial input of energy called activation energy.
Energy release is to condensation as energy input is to?
Energy release is to condensation as energy input is to vaporization. Vaporization requires energy input to happen, while condensation releases energy.
In a chemical reaction bonds are broken or?
Chemical reactions can be either endothermic (that is, where bonds broken) or exothermic (i.e. where bonds are formed). The former requires thermal energy input; the latter releases heat energy as bonds are formed.
What kind of chemical reaction needs a constant supply of energy?
If a reaction requires a constant input of energy, the products are higher in energy than the reactants. This type of reaction is known as endothermic, since it involves an increase in energy of the system. Conversely, reactions that release energy are known as exothermic.
What is the efficiency of a machine that requires 120J of input energy to do 35 J of useful work?
The idea is to divide the useful work by the input energy.
