Answer:
Explanation:
Given
initially steam is at
and converted to
ice
Let m be the mass of steam
latent heat of fusion and vaporization for water is


Heat required to convert steam in to water at 

Heat required to lower water temperature to 



Heat required to convert
water to ice at
is





So this energy is equal to kinetic energy of bullet of mass m moving with velocity v




The answer is 167 pounds.
Answer:
92 protons
Explanation:
The mass number is
238
, so the nucleus has <u>238 particles</u> in total, including <u>146 neutrons</u>. So to calculate the number of neutrons we have to subtract: 238 − 146 = 92
