What is meant by rate of burning for explosives?
In this case rate of burning means The amount of explosive converted into heat and energy per unit time. or the amount of explosive consumed per second or per minute.
Do energy efficient bulbs really reduce an electric bill?
Yes A 100watt light bulb left on for 10 hours will use a much electricity as a 1 Kilowatt fire left on for one hour. An energy efficient light bulb giving out the same amount of light as a 100watt bulb, only actually uses 20watts of electricity. That is 1/5th of the electricity, it will need to be on for 50 hours to use as much as a 1 Kilowatt fire left on for one hour. This will reduce your electric bill but the bulbs are more expensive than old 100watt bulbs (but the energy efficient bulbs last 6-8 times longer! so this balances out).
How long does it take for a 100-watt light bulb to consume 100 watts of energy?
it will take more than100 watts until the filament reaches operating temperature so perhaps a second to get as low as 100 watts . then 100Watts there after until 300 hours pass then 0 watts if you mean 100Watt hours then the answer is 1 hour and the hour will cost about a penny
How can you convert chemical energy to mechanical energy?
By burning
What substance are produced and consumed in photosynthesis?
Oxygen+glucose are produced, CO2+water+ the energy from the sun light are consumed
What is meant by rate of burning for explosives?
In this case rate of burning means The amount of explosive converted into heat and energy per unit time. or the amount of explosive consumed per second or per minute.
Is there energy consumed at any time during an exothermic reaction?
Burning is an exothermic reaction, but to get gas, or wood, or coal to burn you must start by using some energy to get the reaction started. After it starts it will produce enough energy to keep the reaction going and to release excess energy. This energy put in to start the process is called the activation energy.
Is water vapor to ice consumed or released energy?
consumed
Why the first and second law of thermodynamics may be states you can not get ahead and you can not break even?
According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.
Burning fuels which energy converted into heat energy?
Burning fuels, chemical energy is converted to heat energy
Is chemical energy created by burning fuels?
Chemical energy is not created by burning. Chemical energy is already present just converted into heat/light energy by burning.
What is difference in energy density and power density?
Energy density is the amount of power that can be stored ( in for example capacitance) to be then consumed over time, whereas power density is how much energy is consumed quickly like the energy stored in a capacitance can be consumed very quickly.
When covalent bonds are broken energy is released?
No, energy is consumed.
What energy consumed by motorcar moving in town as compared to the energy consumed by a cyclist moving the same distance is approximately?

What type of energy is a burning match?
A burning match uses up heat energy and light energy
Is burning coal mechanical energy?
