Does matter gain weight when it expand?
No, matter does not gain weight when it expands. The weight of an object is determined by its mass and the gravitational force acting on it. When matter expands, its mass remains the same, so its weight does not change. However, the density of the material decreases as it expands.
Does a 2-kg block so solid iron have twice as much mass as a 1-kg block of iron?
yes
Does earths gravity pull more strongly on a block of wood or on a block of iron having the same size?
Earth's gravity pulls equally on both a block of wood and a block of iron of the same size. Gravity depends on the mass of the objects, not their material composition. The weight experienced by each block will be based on their mass, with the iron block likely to be heavier due to its higher density.
If you Compare a 1kg block of solid iron a 2kg block of solid iron has twice as much?
Oh, what a happy little question! If you compare a 1kg block of solid iron to a 2kg block, the 2kg block does indeed have twice as much iron as the 1kg block. It's like adding another layer of paint to your canvas - it just makes everything a little bit brighter and more wonderful.
Why does an iron nail gain weight on rusting?
When an iron nail rusts, it reacts with oxygen in the air to form iron oxide (rust), which has a greater mass than iron alone. This increase in mass causes the iron nail to gain weight during the rusting process.
Why does iron block displaces more water than a copper block of the same weight?
Iron is denser than copper, so a block of iron will displace more water than a block of copper of the same weight because the iron block takes up less space for the same mass. This means that the iron block will sink deeper into the water, displacing more water.
What is the density of an iron block that has a mass of 15.8 grams and a volume of 2 cubed centimeters?
The density of the iron block is 7.9 g/cm^3. This is calculated by dividing the mass (15.8 grams) by the volume (2 cm^3).
How are mass and weight affected if a block of iron is transported to the moon?
The mass of the block remains the same because mass is a measure of the amount of matter in an object. However, the weight of the block would decrease on the moon compared to Earth due to the moon's lower gravity. Weight is the force with which gravity pulls on an object's mass.
Iron has a density of 7.874 gcm 3 What is the mass of a rectangular block of iron with dimensions of 3.000 cm by 4.000 cm by 5.000 cm?
To find the mass of the block, first calculate its volume: 3.000 cm * 4.000 cm * 5.000 cm = 60.000 cm^3. Then, multiply the volume by the density of iron: 60.000 cm^3 * 7.874 g/cm^3 = 472.44 g. Therefore, the mass of the block is 472.44 grams.
Does an iron nail gain mass or loss mass when it rusts a form of burning?
When an iron nail rusts, it actually gains mass. Rusting is a chemical reaction between iron, oxygen, and moisture, producing iron oxide (rust). During this process, the iron combines with oxygen from the air, which adds to the overall mass of the nail. While rusting is not a form of burning, it does involve an oxidation reaction similar to combustion.
What has maximum inertia if all have the same volume wooden block or glass block or iron block or aluminum block?
Inertia is directly proportional to mass.If all of the blocks have the same volume, they will have different masses because those materials have different densities. Mass = density x volume.The object with the highest density will have the highest mass and therefore the highest inertia.Densities:glass ~ 2500kg/m3 (but can range from 2000 to 8000kg/m3)aluminum 2700kg/m3iron 7850kg/m3wood ~ 550kg/m3 (but can range from 150 to 1350kg/m3)
Do teenage boys need more iron?
Yes, teenage boys need more iron due to their increase in muscle mass. In addition, their blood volume expands and they have a rise in hemoglobin during the growth spurt of adolescence.
