Question
Compare the density of a kilogram of stone with a kilogram of feathers.
Metals are usually more dense than wood. Pick the statement below which accurately compares metals to wood.
The molecules in metal are usually more tightly packed than the molecules in water. Most metals will sink in water. Pick your conclusion from this list.
Which do you assume would weigh more: a shoe box full of iron or a shoe box full of feathers?
Both are equal weight

A hot iron is thrust into a barrel of water. What do you expect to happen to the water?
Now a second iron, not quite as hot as the first, is thrust into a second barrel of water, identical to the first. How do you expect this to compare to the first situation?
Two cubes of ice are set into two identical glasses of water. Cube A is twice the size of cube B. Which cup do you think will be colder after both ice cubes melt?
Specific heat depends on several factors. Pick the factor below that you suspect will not affect specific heat.
Water and iron have quite different specific heats. Iron heats up more than water when the same amount of heat energy is added to it. Which one of these substances do you deduce has the higher specific heat?
Which of the following do you think might cause a change in the specific heat of an object?
Material A has a specific heat of 100 J/kg-K and Material B has a specific heat of 200 J/kg-K. If the two materials start at the same temperature and have heat energy added at the same constant rate, which would you expect to reach a higher temperature first?
.Compare the density of a kilogram of stone with a kilogram of feathers.
They are the same. Feathers are more dense. Stone is more dense.Explanation / Answer
Density= mass/ volume
1) feathers will consume more volume than stone so feathers will have a less density than stones.
2) metals have more density that means they have a more mass per unit volume than wood
3) metal are more sense than water as they easily sink in water
4) as the volume is constant the higher the density the higher the weight so iron will weigh more than water
