List five physical properties?

Answers

Some examples of physical properties are:

color (intensive)

density (intensive)

volume (extensive)

mass (extensive)

boiling point (intensive): the temperature at which a substance boils.

melting point (intensive): the temperature at which a substance melts.

Physical Properties are used to describe how something is. Examples include:

1. Color
2. Shape
3. Size
4. Density
5. Melting/ Boiling point
6. Ordor

Physical changes: occur when matter changes form but not composition (Ex: ice is still H2O). Examples of physical change are:

1. Phase Change (Boiling, melting, freezing, etc.)
2. Size and/ or shape change
3. Dissolving
4. No Color Change (Except dyes)

Which requires the removal of heat, melting or freezing?Is it evaporation? What is it? Why?

Answers

Freezing. If you take away energy from something, (lower its temperature), it will freeze. If you add heat to something, it will melt if it is a solid and evaporate if it is a liquid.

When you add energy to something, the atoms which comprise the substance jiggle and vibrate, meaning that on a large scale, a solid will become a liquid, and a liquid will become a gas.

Freezing, just think about it, the colder it gets the more likely there is going to be snow/ hail/ ice

Abrasion and carrying load containing sediment and deposition are examples of? land erosion
load effect
water erosion
none of the above

Answers

C : water erosion is the correct answer. I know this because water from the sea, pool, lake, et cetera could erode the ground surrounding the water because the pressure of the water and the water seeping into tiny cracks, and even holes in the ground cause sediment to mix with the water causing abrasion and erosion. Hoped I helped!

Answer:

the correct answer is water erosion (c.)
