The answer depends on the density as well as the shape of the 100 kg mass.
No, it wouldn't. a sugar cube would melt a lot faster in a cup of Hot water. the hot water helps it desolve more evenly than cold water.

it is water iwould call this a ice cube
One is the temperature of the water could be warmerSecondly when an ice cube is in water, conduction takes place. The kinetic energy of the water particles more time.moves to the ice causing it to melt. When in air radiation or convection must take place which will take
Any amount of water can make an ice cube. It's not the amount that determines if water will become ice, it is the temperature. The water just needs to be at a temperature of 0oC or lower, and it will become ice.
It would depend on the size of the cube!
Archimedes' principle: an object in water experiences an upward lift equal to the weight of the volume of water being displaced. volume of water displaced = 8000 cm3 weight of water displaced ~ 1 g/cm3 at room temperature and sea level weight of cube in air = 16000 kgf lift ~ 8000 gf = 8 kgf weight of cube in water = 16000 kgf - 8 kgf = 15992 kgf
When an ice cube is dropped into boiling water, heat will flow from the boiling water to the ice cube. This transfer occurs because heat moves from areas of higher temperature (the boiling water) to areas of lower temperature (the ice cube). As the ice absorbs heat, it will begin to melt, and the surrounding water will cool slightly until thermal equilibrium is approached.
When ice cube is submerged on water...The upthrust created on the ice cube by water is equal to the weight of the displaced water...when the ice cube is melting its volume changes but its weight remains the same and its exactly equal to the weight of displaced water when the ice cube was frozen...therefore the 'volume of of melted water' fits exactly to the 'volume of displaced water when the ice cube was frozen'... So the water level does not change! -Shenal K Mendis ;)
Heat will flow from the boiling water to the ice cube, causing the cube to melt and the water temperature to decrease. The final temperature of the system will depend on the masses and initial temperatures of the ice cube and boiling water.
The ice absorbs heat from the water, which is why it melts
Yes, a sugar cube dropped in hot water is an example of diffusion. The sugar molecules move from an area of higher concentration (the sugar cube) to an area of lower concentration (the hot water) until they are evenly distributed. This process is a type of diffusion called passive diffusion.
the ice cube's temperature is higher than the surrounding water, causing heat transfer from the water to the ice cube. This heat transfer raises the ice cube's temperature, melting it into water until both reach thermal equilibrium.
-- The aggregate density of the wood block is 700/1000 = 0.7 the density of water. -- So, as soon as the wood has displaced 0.7 of its volume in water, it has displaced its entire weight in water, and floats. -- The wood floats with 0.7 of its volume below the surface and 0.3 of its volume above it.
The ice cube will float higher in sea water than it will in pure water (more of it will be above the water level). This is because the salt in sea water makes it more dense than pure water, meaning that less water must be displaced to account for the mass of the ice.
There are different formulas for different shapes, but it think you can also do something along the lines of compound volume. You can also measure the displaced water with the object in the water, and subtract.
When a sugar cube is dropped in cold water, the sugar molecules start to dissolve due to diffusion. Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration to achieve equilibrium. As the sugar molecules spread out in the water, the sugar cube eventually dissolves completely.
