Answer: The amount of heat required by water is 418.6 J

Explanation:

To calculate the heat absorbed by water, we use the equation:

[tex]q=mc\Delta T[/tex]

where,

q = heat absorbed

m = mass of water = 10 g

c = heat capacity of water = 4.186 J/g°C

[tex]\Delta T[/tex] = change in temperature = 10°C

Putting values in above equation, we get:

[tex]q=10g\times 4.186J/g^oC\times 10^oC\\\\q=418.6J[/tex]

Hence, the amount of heat required by water is 418.6 J
