Because a lot of the energy used to hear up the room is lost to the surroundings eg for every 100 J of energy stored in coal and released as heat about 25 J is used to heat u the room whilst the rest is lost to the surroundings
Coal fires release carbon dioxide (CO2), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOx), particulate matter, and other pollutants into the atmosphere, contributing to air pollution and climate change.
Yes, coal is commonly used as a fuel for fires due to its high energy content and ability to burn for a long time. It is often used in fireplaces, stoves, and for heating purposes.
Coal dust burns faster than solid coal due to its increased surface area, allowing for more efficient combustion. This can lead to more intense and quicker fires when coal dust is ignited.
No, wet coal can be difficult to burn effectively because the water content reduces the coal's energy output by absorbing heat energy during combustion. It can also lead to increased emissions and inefficient burning, as the water needs to be evaporated first before the coal can ignite and burn properly. It is recommended to use dry coal for more efficient and cleaner burning.
Coal is primarily used as a source of energy for generating electricity and in industrial processes such as steel production. It is burned to produce heat, which is then used to create steam that drives turbines to generate electricity. Coal also has other industrial uses, such as in the production of cement and in chemical processes.
It was coal burning and inefficient by today's standards.
people used to use coal fires, and gas and electric fires have been round for years and years, but coal fires was the prefered method
YES And to make it extra special there is an underground coal fire that causes brush fires every years about 20 miles from my house.
coal was used to warm up homes and to make fires
Coal was made to burn fires and help with electricity it is also used to heat waters.
No the coal will turn in to ashes and it is made to make long lasting fires.

Coal fires release carbon dioxide (CO2), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOx), particulate matter, and other pollutants into the atmosphere, contributing to air pollution and climate change.
if coal didn't exist we would have fires because that's how they were first made
It is impossible to determine the length of time that some fires have been burning. Coal fires, for example, can burn for decades, and even longer. One of the world's longest burning coal fires can be found at the Burning Mountain Reserve at Wingen, in northern New South Wales, Australia. This coal fire is estimated to have been burning for 6000 years.
They use coal and animals skin
Yes, coal is commonly used as a fuel for fires due to its high energy content and ability to burn for a long time. It is often used in fireplaces, stoves, and for heating purposes.
