Physics
1 answer:
olga nikolaevna [1]4 years ago
8 0

Answer:

The number of calories needed is 6c.

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.
