Density. This is quantified as a mass over a volume, so if you know the volume, the density will allow you to determine the mass of an object. Density equals mass divided by volume so mass is equal to density multiplied by volume.
When the volume is increased while the mass remains, the density increases. One way to increase volume is by reducing the temperature of objects especially gases. This is how air conditioning and fridges work, cooling the air which will move down as denser objects sink. This will allow the whole room or fridge to be cooled down instead of just one small area.
Translucent objects allow some light to pass through them, but they also scatter the light in different directions. This scattering causes the image of objects seen through the translucent object to become distorted and less clear. The multiple paths the light takes through the translucent object results in a blurry or fuzzy appearance when looking at objects behind it.
Pulleys can be helpful because they provide a mechanical advantage, allowing for easier lifting of heavy objects by distributing the force needed over multiple ropes or cables. They also allow for changes in the direction of force, enabling more flexibility in moving objects. Lastly, pulleys can help in lifting objects to higher heights by reducing the amount of effort required.
No, solid objects do not allow light to pass through them because the particles are tightly packed and do not allow for the transmission of light. Materials such as glass and plastic are transparent solids that allow light to pass through due to their molecular structure and arrangement.

No, periscopes allow you to observe objects while you are hidden.
Increase the surface area as much as possible with little walls, or do really really high walls to increase the volume, which will increase the density, which will allow it to carry heavy things. (even a full soup can!) -Science project experience

Sound is a pressure wave. Objects that "allow" sound to travel through them could be called wave guides.
