The amount of energy needed is 2093 J
Explanation:
The amount of energy needed to increase the temperature of a substance by [tex]\Delta T[/tex] is given by the equation
[tex]Q=mC\Delta T[/tex]
where
m is the mass of the substance
C is its specific heat capacity
[tex]\Delta T[/tex] is the increase in temperature
For the water in this problem, we have
m = 50.0 g = 0.050 kg
[tex]C=4186 J/g^{\circ}C[/tex] (specific heat capacity of water)
[tex]\Delta T=10.0^{\circ}C[/tex]
Therefore, the amount of energy needed is
[tex]Q=(0.050)(4186)(10)=2093 J[/tex]
