# A cube of water 10 cm on a side is placed in a microwave beam having . The microwaves illuminate one face of the cube, and the water absorbs of the incident energy. How long will it take to raise the water temperature by . Assume that the water has no heat loss during this time.

The raise of the water temperature is

See the step by step solution

## Step 1: Definition of Electromagnetic fields and Waves:

A charge near its surroundings produces an electric field, which is a force. When other charges are brought near this field, they are subjected to this force. N/C (Force/Charge) is the SI unit for electric fields.

## Step 4: Equation:

Now, Find value for :

## Step 5: Substitute the values in equation:

Finally, find the values for :

## Step 6: Final Result:

The change in the quantity of water is .
