<u>Answer:</u> The increase in temperature is 10°C

<u>Explanation:</u>

To calculate the change in temperature, we use the equation:

$q=mc\Delta T$

where,

q = heat absorbed = 200 kCal = 200,000 Cal (Conversion factor: 1 kCal = 1000 Cal)

m = mass of water = 20 kg = 20000 g (Conversion factor: 1 kg = 1000 g)

c = specific heat capacity of water = 1 Cal/g.°C

$\Delta T$ = change in temperature = ?

Putting values in above equation, we get:

$200,000Cal=20,000g\times 1J/g.^oC\times \Delta T\\\\\Delta T=\frac{200,000Cal}{20,000g\times 1Cal/g^oC}=10^oC$

Hence, the increase in temperature is 10°C
