Question

1.20) what is the density of water at room temperature?
a. 1 g/cm³
b. 10 g/cm³
c. 100 g/cm³
d. 1,000 g/cm³
1.21) objects with a large density tend to _, while objects with a smaller density tend to _.
a. sink; float
b. float; sink
1.22) _ is how something feels.
a. mass
b. texture
c. volume
1.23) what do all these units describe?
a. density
b. size
c. elasticity
1.24) which tool would best fill in the chart?
a. spring scale
b. metric ruler
c. balance beam

Explanation:

• 1.20: The density of water at room temperature is a well - known physical property. Water has a density of \(1\ g/cm^{3}\) at room temperature.
• 1.21: According to the principle of buoyancy, objects with a density greater than the fluid they are in (e.g., water) will sink, and objects with a density less than the fluid will float.
• 1.22: Texture is the quality of a surface or substance, which is related to how it feels. Mass is the amount of matter in an object, volume is the amount of space an object occupies.
• 1.23: Length, mass, area, and volume are all related to the size or extent of an object. Density is mass per unit volume, and elasticity is the ability of a material to return to its original shape after being deformed.
• 1.24: A metric ruler is a tool used to measure length. A spring scale is used to measure force (related to weight, which is a force due to gravity), and a balance beam is used to measure mass.
