Answer:

The number of calories needed is 6c.

Step-by-step explanation:

The amount of energy
Q needed to raise the temperature
\Delta T of water of mass
m is


Q = mC\Delta T

where
C = 1cal/g\cdot C is the specific heat capacity of water.

Putting in numbers into equation (1), we get:


Q = (2g)(1)(3^oC )\\


\boxed{Q = 6\:cal }

which is the number of calories needed.
