If you have a mass of 3kg of gas how much energy can you create from burning it using the formula E mc2?
To calculate the energy released from burning 3kg of gas using E=mc^2, you need to know the speed of light (c) and convert the mass to energy using the formula. The speed of light is approximately 3 x 10^8 m/s. After plug in the values, you would find that the energy released is a very large amount, as even a small mass converted to energy can produce a significant amount of energy.
How do you know why thermal energy by burning matchstick?
When a matchstick is burned, the thermal energy is released as a result of the chemical reaction between the match head (containing sulfur and potassium chlorate) and the striking surface (containing red phosphorus). This reaction generates heat energy, causing the matchstick to ignite and produce a flame.
How do you calculate heat energy when you know volume and temperature?
To calculate heat energy when you know volume and temperature, you would need to use the formula Q = mcΔT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature. Given volume, you would also need to know the density of the substance to calculate the mass.
Name 5 different sources of heat?
We know that chemical, mechanical, electrical and nuclear phenomenon create thermal energy. Combustion (burning) is chemical, and we know that creates thermal energy. Mechanical action creates heat, and your vehicle's brakes know this well. Electrical energy can be used to create heat in resistive heating elements. Nuclear reactions result in a jump in the energy of atoms and molecules involved, and this is expressed as heat.
What is the kinetic energy (in J) of an N2 molecule moving at this speed?
The kinetic energy of a molecule is given by the formula KE = 0.5 * m * v^2, where m is the mass of the molecule and v is its velocity. For an N2 molecule moving at a certain speed, you would need to know the speed and the mass of the molecule to calculate the kinetic energy in joules.
What energy was given by the burning matchstick?
The energy given off by the burning of a match is called thermal energy. If you want to know the amount of energy, you then need to have more information related to the mass and material of the match.
What energy was given of by burning the matchstick?
The energy given off by burning a matchstick is released in the form of heat and light. During the combustion process, the chemical bonds in the matchstick are broken, releasing energy that manifests as both heat, which warms the surroundings, and light, which we see as the flame.
What types of energy includes the burning of wood or animal dropping?
I want to know knot to answer! Geez
The process of storing or burning more energy to maintain the body best weight is called what?
jfjgakjkjdfkajfkascarb burning i dont know if it right but it sure is a better answer than jfjgakjkjdfajkas :)
How do you know that a burning of candle wax is an exothermic change?
When a candle burns, it releases energy in the form of heat and light, indicating that it is an exothermic process. This is because the products formed during the burning reaction have lower potential energy than the reactants, leading to a release of energy to the surroundings.
What is the energy change in burning ethanol?
The energy change in burning ethanol is exothermic, meaning it releases heat energy. During combustion, ethanol reacts with oxygen to form carbon dioxide and water, releasing energy in the process.
Why cant you get candle material back after burning?
Candle while burning, its wax gets burnt and matter gets changed into heat and light energy. These get radiated and pass away. So we cannot get back the candle material. Energy can neither be created nor be distroyed. This cannot be violated in any case. But matter can be changed into energy. So to get back the matter we have to know the technique to collect heat and light energy and know the skill to change it back to matter.
What are 4 useful burning reactions?
I don't know for but I do know three which are: burning gas to cook food, burning coal to make electricity and burning diesel to run a car or bus, etc.
What is light frequencies?
The frequency of a wave of light is given by speed of light/wavelength, or by energy/Planck's constant.If you know the frequency or the energy associated with the light, it is easily calculated.
Describe the sequence of energy changes beginning with the sun and ending with burning wood for a campfire?
See, I don't exactly know if this is correct or not. The suns energy is mechanical energy and it shines down on some wood and starts heating it up. the wood starts burning and that is chemical energy. Check with someone else to make sure it is correct.
When was The World Should Know - Burning Spear album - created?
The World Should Know - Burning Spear album - was created in 1993.
How we know a chemical change has occurred when burning a candle?
Burning is a chemical reaction, an oxydation.
