1.3 × 10⁶ Joules of heat is required to raise the temperature of 5 kilograms of coal from 20°C to 220°C
<h3>Further explanation</h3>
Specific Heat Capacity is the amount of energy needed to raise temperature of 1 kg body for 1°C.
<em>Q = Energy ( Joule )</em>
<em>m = Mass ( kg ) </em>
<em>c = Specific Heat Capacity ( J / kg°C ) </em>
<em>Δt = Change In Temperature ( °C )</em>
Let us now tackle the problem!
<u>Given:</u>
mass of coal = m = 5 kg
change in temperature = Δt = 220 - 20 = 200°C
specific heat capacity of coal = c = 1.3 × 10³ J/kg°C
<u>Asked:</u>
heat required = Q = ?
<u>Solution:</u>
<h3>Conclusion:</h3>
1.3 × 10⁶ Joules of heat is required to raise the temperature of 5 kilograms of coal from 20°C to 220°C
