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:

$Q = mC\Delta T$

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,

$Q = (2\ kg)(4.18\ KJ/kg.^oC)(16^oC)$
