How much energy does it take to raise the temperature of 2kg water from 10 Celsius to 26 Celsius? The specific heat capacity of water is 4.18kj/(kg C).
How much energy does it take to raise the temperature of 2kg water from 10 Celsius to 26 Celsius? The specific heat capacity of water is 4.18kj/(kg C).
Answer:
Q = 133.76 KJ
Explanation:
The amount of heat energy required to raise the temperature of the water can be calculated by the following formula:
[tex]Q = mC\Delta T[/tex]
where,
Q = Heat Energy Required = ?
m = mass of water = 2 kg
C = Specific Heat Capacity of Water = 4.18 KJ/kg°C
ΔT = change in temperature = 26°C – 10°C = 16°C
Therefore,
[tex]Q = (2\ kg)(4.18\ KJ/kg.^oC)(16^oC)[/tex]
Q = 133.76 KJ
