Consider the two spheres shown here, one made of silver and the other of aluminum. The spheres are dropped from a height
of 2.4 m.
Composition = aluminum
Density = 2.70 g/cm
Volume = 196 cm3
Composition = silver
Density = 10.49 g/cm
Volume = 196 cm

C. which metal is less dense

Evaporation: this is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas). water vapour droplets join together to make clouds! condensation: this is when water vapour in the air cools down and turns back into liquid water.

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
