Unlike the ice cubes in a cold drink , dry ice doesn't melt to become liquid at all. Instead, at room temperature, it changes directly from a solid to a gas a process called sublimation . This expansion causes a rapid temperature drop, and some of the carbon dioxide freezes into solid pellets of dry ice.

<span>Data:
Initial velocity upward: Vo = 5.00 m/s ,
Initial position: h = 40.0 m above the ground
Type of motion: free fall.
A) Compute the position of the sandbag at a time 1.05 s after its release.
Equation: y = h + Vo*t - g*(t^2) / 2
y = 40.0 m + 5.00 m/s * 1.05s - (9.8 m/s^2) * (1.05 s)^2 / 2 = 39.8 m
B)Compute the velocity of the sandbag at a time 1.05 s after its release.
Equation: Vf = Vo - g*t
=> Vf = 5.00 m/s - (9.8m/s^2) * (1.05 s) = - 5.29 m/s
Negative sign means that the sandbag is going down.
c) How many seconds after its release will the bag strike the ground?
Equation:
y = yo + Vo*t - g*(t^2) / 2
0 = 40.0 + 5.00t - 4.9 t^2
=> 4.9 t^2 - 5t - 40 = 0
Use the quadratic formula and you get: t = 3.41 s

When water vapor condenses during the formation of clouds, energy is released into the atmosphere through the process of latent heating.
Huge amounts of solar energy are absorbed during the evaporation process. There is no thermal equilibrium in protostars. They emit radiation that causes them to lose energy, but their interior temperatures aren't hot enough to start nuclear fusion to replenish the energy. They consequently tighten and warm up. Fusion can replace the energy they are losing once they are heated enough on the inside (about 107 K). The gas atoms start to collide more and get closer together as the cloud gets smaller, which warms them up. The cloud keeps shrinking and heating up until the force of gravity is balanced by the pressure from the heat.
