What is the energy required to raise the temperature of 2 g of water by 10° C?

Given : 

Mass of the water $= 2 g$

Change in Temperature $= 10° C$

To Find : 

Energy required to raise the temperature of 2 g of water by 10° C.

Solution : 

$\Delta t=\frac{Q}{m\times s}$

$\Delta t$ - Change in temperature

Q - Energy required

m - mass

s - specific heat capacity of water

Specific heat capacity of water $= 4.18 J$

$10 =\frac{Q}{2\ \times 4.18}$

$10\times 2 \times 4.18 = Q$

$83.6 = Q$

$Q = 83.6$

So, the energy required to raise the temperature of 2 g of water by 10°C is 83.6 Calories.
