A pianola changes pitch by varying the speed at which the paper music roll is fed through the mechanism. Faster speed increases pitch, slower speed decreases pitch. Volume is controlled by adjusting the amount of air flowing through the instrument, usually done through a foot-operated bellows pedal system.

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.
Matter that does not change in shape or volume?

What is the weight of a pianola?
The weight of a pianola can vary depending on its size and model, but on average, they can weigh between 300-600 pounds. It is important to note that pianolas are heavy and may require multiple people to move or transport safely.

No it doesn't change its volume
Why do solids not change their volume?
it cannot change its volume because it has a definite shape and the electrons are tightly packed but it can change its volume when there is a slight change in temperature.
