This is one of those ideas that have just grown with us as we developed from our ape-like ancestors. However, Archimedes is famous for figuring out how to measure it.

Is volume a physical or a chemical change?

Volume is a physical quantity not a change. However CHANGE in volume is a physical change.


Find the change in volume of an aluminium sphere of 0.4m radius when it is heated from 0 to 100degree centigrade?

The change in volume of an object due to temperature change is given by the coefficient of volume expansion (α), which for aluminum is about 0.000023 per degree Celsius. Given the initial temperature change from 0 to 100 degrees Celsius, the total change in volume can be calculated using the formula: ΔV = V * α * ΔT, where V is the initial volume, α is the coefficient of volume expansion, and ΔT is the change in temperature. Substituting the values, you can find the change in volume of the aluminum sphere.


Can a increase in density result from an increase in mass and no change in volume?

Yes. Density is mass/volume so if mass increases so does density if volume does not change


How does the volume of a can change when it is crushed?

When a can is crushed, the volume decreases due to the change in shape. The material inside the can gets compacted, reducing the amount of space it occupies. The actual change in volume depends on the extent of the crushing.


Which phase can change shape and can also easily change its volume?

The phase that can change shape and easily change its volume is gas. Unlike solids, which maintain a fixed shape and volume, and liquids, which have a fixed volume but take the shape of their container, gases have neither fixed shape nor fixed volume. They expand to fill the entire space of their container, adapting both shape and volume based on environmental conditions.
