Snow tends to sublime outside during cold, clear winter days when the atmospheric pressure is low. during this process,
a) the density of water is decreasing.
b) the temperature of the water is decreasing.
c) the volume of the water is decreasing.
d) the amount of water is increasing.

Agas is contained in a vertical, frictionless piston–cylinder device. the piston has a mass of 3.2 kg and a cross-sectional area of 35 cm2. a compressed spring above the piston exerts a force of 190 n on the piston. if the atmospheric pressure is 95 kpa, determine the pressure inside the cylinder.

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.
