1.) What is the maximum number of grams of liquid water at 10C that can be heated to 30C by the addition of 84 joules of heat?

m = 1 gram

Explanation:

Given that,

Heat, Q = 84 J

The temperature increases from 10°C to 30°C.

We need to find maximum number of grams of liquid water. We know that the heat required is given by :

c is specific heat of water, c = 4,200 J/kg°C

Use the above formula to find m. So,

or

m = 1 gram

So, the required mass is 1 gram.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
