Answer:
1.5g/cm³
Explanation:
density=mass÷volume
mass= 1.5kg (<em>c</em><em>h</em><em>a</em><em>n</em><em>g</em><em>e</em><em> </em><em>i</em><em>n</em><em>t</em><em>o</em><em> </em><em>g</em>) = 1500g
volume of the cube = 10×10×10 = 1000cm³
density= divide 1500g÷1000cm = 1.5g/cm³
<h2>
Density= 1.5g/cm³</h2>
YOUR WELCOME!
Some physical properties would be:
appearance, odor, density, and magnetism.
Some chemical properties would be:
flammability, reaction to water oxygen or acid, decomposition caused by light or heat, and tendency to corrode.
Hope this helps. (;
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.
<span>A PRECIPITATE is a solid that forms inside of a mixture.
When we add lemon juice to milk, the lemon juice causes lumps to form inside of the milk. SOLID lumps.
We call them "curds." So, we end up with SOLID curds, formed inside of liquid whey.
if that doesn't help its B</span>
Here we have to identify the sample which need more energy to heat the sample 1 degree Celsius.
Among the given elements magnesium will require more energy than the others to heat.
As per the definition of specific heat of a compound, the amount of heat required to increase the temperature of the material 1 degree Celsius is the specific heat of the material.
The given data are-
substance specific heat
Lead 0.129
Tin 0.21
Silver 0.235
Iron 0.449
Calcium 0.647
Granite 0.803
Aluminium 0.897
Magnesium 1.023
From the given data lead, magnesium, iron and aluminium have the specific heat 0.129, 1.023, 0.449 and 0.897 respectively. Thus magnesium will require more energy than the others to heat.
