For a physics experiment, a solid cube is suspended from a spring scale. The gravitational force exerted on the cube is 0.714 N as measured when the object is suspended from a spring scale. When the suspended cube is submerged in water (ρ = 1000 kg/m3), the scale reads 0.450 N.  What is the volume of this cube in cm3?  Notice: 1 m3=(100cm)3=1,000,000 cm3.

Different amounts of three substances –  0oC ice-cold water 0oC ice cubes -4oC ice cubes are separately added to 300 g of warm water at 25oC. Assume all the mixtures reach the same final equilibrium temperature.  Rank the amount of ice or water needed, from the most (#1) to the least amount (#3).

The same amount of three substances –  0oC ice-cold water 0oC ice cubes -4oC ice cubes are separately added to 300 g of warm water at 25oC. Rank the mixtures by their final equilibrium temperatures, from the hottest (#1) to the coldest (#3).
