The density of a substance is equal to 2.5 g/mL. The sample you have has a mass of 13g. How much space does this object take up?
Answers
Answer:
5.2mL
Explanation:
We need to find space
Space = Volume
Volume = Mass / Density
= 13 / 2.5
You get 5.2mL as the answer

The terrarium model shows the many different aspects of life. The dirt shows the geosphere, which is the ground thaat the plant can grow in. The biosphere is represented by the plant growing, and the hydrosphere is the water that you use to water the plant, and the condensation that will gather on the lid. The atmosphere is the air inside the jar.
Explanation:
Each of the above show how the environment works.
An object’s mass is determined to be 32.5 g. When the object is placed in a graduated cylinder containing 175 mL of water, the water in the cylinder rises to a level of 187.5 mL. What is the density of the material?
Answers
When the object is placed in a graduated cylinder containing 175 ml of water, the water in the cylinder rises to a level of 187.5 ml , this implies that volume of content in the container has increased , the increased volume is volume of the object placed
So, Volume of object
= Increased Volume - Initial volume
= > 187.5 -175
= > 12.5 ml
Since 1 ml = 1 cm³ we can write
[tex]\quad[/tex]12.5 ml = 12.5 cm³
Now,
[tex]\green{ \underline { \boxed{ \sf{Density= \frac{Mass}{Volume}}}}}[/tex]
Putting Values -
[tex]\begin{gathered}\\\implies\quad \sf Density = \frac{32.5}{12.5} \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \sf Density = \frac{325}{125} \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \sf Density = 2.6 g/cm^3 \\\end{gathered} [/tex]
>> The density of the material is 2.6 g/cm³

D is the answer
Explanation:
First of all, conservation is when you conserve resources, or use them less, to be better for the environment. Using a gas powered car does not, as carbon monoxide and other toxic gases are sent into the atmosphere. Using a disposable bag is bad because the plastic is sent away to the environment every time you shop. Leaving water running when you brush your teeth wastes water and is bad for the environment. Recycling aluminium cans and glass bottles is good for the environment, and is conserving resources because the cans and bottles are reused, so instead of wasting, you are reusing.

Answer:
- Independent Variable: Sand, water (variable that changes)
- Dependent Variable: Heat (Sun)
- Control Variables: Environment, container, therometer
Hypothesis: If the sand and water both receive solar radiation, the sand will heat up faster.
Materials:
- 2 thermometers
- 2 plastic boxes (These should be identical)
- Sand
- Water
Procedure:
- Pour sand into one of your plastic boxes to a depth of two inches. Pour water into the other plastic box to a depth of two inches. The sand box will represent land while the water box represents a body of water.
- Place the two boxes in a location that receives direct sunlight and place one therometer in the sand, and the other in the water.
- For a period of 30 minutes, check the temperature of both boxes every 10 minutes. Record the temperatures in a chart/graph
Observations: The temperature of the land (sand) was higher than the water.
Results: Land absorbs much more solar radiation than water, due to the fact that most land surfaces are darker than water, thus attracting heat. Water typically reflects solar radiation that reaches its surface back to the atmosphere. As a result of land absorbing more solar radiation, the land also retains more heat. This validates my hypothesis of the land (sand) heating faster.
