How much heat energy is required to raise the temp of 5 kilograms of coal from 20 degree celsius to 220 degrees celsius?

314 j
6,573 j
4,187,000 j
1,314,718 j

You need the specific heat of coal to answer that question, and that depends somewhat upon the type. Did they mention a value to use? This article:
AIChE Journal Volume 31, Issue 10 , Pages 1714 - 1717
mentions a specific heat value of
C = 1.05 kJ/Kg C
That would make the heat required
(1.05 kJ/kg C)* 5 kg * 200 C = 1,050,000 kJ
That is closest to the last of your choices.

doesnt even make since...

To calculate the heat energy required to raise the temperature of coal from 20 degrees Celsius to 220 degrees Celsius, we need to use the equation:

Q = mcΔT

Where:
Q is the heat energy
m is the mass of the coal (5 kg)
c is the specific heat capacity of coal (1.05 kJ/kg°C)
ΔT is the change in temperature (220°C - 20°C = 200°C)

Plugging in the values:

Q = (5 kg)(1.05 kJ/kg°C)(200°C)
Q = 1050 kJ

Therefore, the correct answer is 1,050,000 J, which is closest to the last option given (1,314,718 J).
