How much energy is in 1kg of coal?
1 kg coal equivalent corresponds to a value specified as 7,000 kilocalories (7,000 kcal ~ 29.3 MJ ~ 8.141 kWh) and thus approximately the calorific value of hard coal which, depending on the type, amounts to between 29.3 MJ/kg (gas-flame coal) and 33.5 MJ/kg (anthracite)..
What is 1 kg in Newtons?
9.80665Kilogram is the base unit of mass in the metric system. 1 kilogram or kilogram-force (kg or kgf) = 9.80665 newtons (N) = 35.2739619 ounces (oz) = 1000 grams (g) = 1000000 milligrams (mg) = 2.20462262 pounds (lbs) = 0.157473044 stones (st).
Does burning wood pollute the air?
Burning Wood Causes Indoor Air Pollution: High levels of smoke pollutants leaking from stoves and fireplaces have been measured in some wood burning homes. … Carbon Monoxide (CO) – An odorless, colorless gas, produced in large amounts by burning wood with insufficient air.
Is it better to burn wood or coal?
* Also, dry wood lights easily, but a coal fire requires much more kindling to get it going. Further, wood burns cleanly, while coal smoke is considered dirty. If you do use coal, anthracite is a relarively clean-burning fuel with a low sulfur content. … That’s one advantage of coal stoves.
How many joules are in a kilogram?
89,875,517,873,681,764 joulesOne kilogram (kg) of mass is equivalent to exactly 89,875,517,873,681,764 joules (according to E=mc2 with m = 1 kg and speed of light c = 299,792,458 m/s).
Is wood clean energy?
From a climate perspective, wood energy is unlike most other renewables. Wind turbines, solar panels and hydropower suck energy out of the environment to produce electricity. Wood must be burned to release its energy, which also releases its climate-changing carbon.
What does 200 joules mean?
Energy absorption/dissipation – This rating, given in joules, tells you how much energy the surge protector can absorb before it fails. A higher number indicates greater protection. Look for a protector that is at least rated at 200 to 400 joules. For better protection, look for a rating of 600 joules or more.
Does burning wood contribute to global warming?
Scientists estimate that the black carbon produced by wood burning is the second most significant contributor to global warming. Black carbon particles in the atmosphere absorb solar heat. This not only heats the atmosphere, but also melts the earth’s snowcaps and glaciers when these particles settle on the ground.
What is the energy equivalent of 1 kg of matter in joules?
This implies, for instance, that 1 kilogram of matter is equivalent to an energy E = (1 kg)×(3×108 m/sec)2 = 9×1016 kg m2/sec2. An energy of 1 kg m2/sec2 is known as 1 joule, for short. The joule is not a unit of energy that is used much in everyday life.
