64. A certain quantity of steam has a temperature of 100.0 °C. To convert
this steam into ice at 0.0 °C, energy in the form of heat must be removed
from the steam. If this amount of energy were used to accelerate the ice
from rest, what would be the linear speed of the ice? For comparison,
bullet speeds of about 700 m/s are common.
A 3.00-g lead bullet at the temperature 30.0°C is fired at a speed of 240 m/s into a large
block of ice at 0°C, in which it becomes embedded. What quantity of ice melts? (The
specific heat of the lead is 128 J/kg.°C, and the latent heat of the ice is 3.33×10$ J/kg.)
A small amount of water of mass m=50 g in a container at temperature T=273 K is placed inside a vacuum chamber which is evacuated rapidly. As a result, part of the water freezes and becomes ice and the rest becomes vapor.
Question: What amount of water initially transforms into ice?
The latent heat of fusion (ice/water): 80 cal/g
The latent heat of vaporization (water/vapor): 600 cal/g
