Q = m*c*delta T
c for coal = 0.24 (depending on its origin)
Q = 5*0.24*(220-20) = 240 Joules
c for anthracite coal is also given as 0.201 which will give an answer of 201 Joules
That would depend on the size of the room and the humidity.
question makes no sense.....
No BTU are required in order to lowerthe temperature of water. All you have to dois place the water in an environment that is cooler than the water is, then stand backand watch the temperatue of the water drop while the BTU flow out of it.
212F.
You just say "degree" followed by the temperature scale, for example, "It was 20 degrees Celsius".
15 0C is the temperature for the required conversion.
The best temperature for growth of bajra is between 20-28 degree centigrade.
Depends on how high you want to raise the gram of water ;).
18 -22 degree C. Rainfall 500mm-1000mm.
Specific heat capacity is the amount of heat energy required to raise the temperature of one unit mass of a substance by one degree Celsius.
The amount of energy required to raise the temperature of one gram of water by one Celsius degree is called the specific heat capacity of water. It is approximately 4.18 joules per gram per Celsius degree.
0 degree centigrade after giving the latent heat.
The amount of heat energy required to raise the temperature of a unit mass of a material by one degree is known as the specific heat capacity of that material. It is a constant value unique to each material and is typically measured in units of J/kg°C.

The amount of cooling required to lower the temperature of a substance by one degree Celsius is known as the substance's specific heat capacity. It depends on the substance's properties and can be measured in joules per gram per degree Celsius (J/g°C) or in joules per kilogram per degree Celsius (J/kg°C).
The quantity of heat required to change an object's temperature by 1 degree Celsius depends on its specific heat capacity and mass. The formula to calculate this is Q = mcΔT, where Q is the heat energy, m is the mass of the object, c is the specific heat capacity, and ΔT is the change in temperature.
