A sample of gold has a mass of 645.0 lb and a volume of 0.5348 ft. What is its specific gravity? Number SG= What are the units o

LekaFEV [45]

Explanation:

The given data is as follows.

Mass of gold = 645 lb, Volume = 0.5348 ft3

Density of water = 62.4 lbs/ft3

It is known that specific gravity is defined as density of substance divided by the density of standard fluid.

Mathematically, Specific gravity = $\frac{\text{density of gold}}{\text{density of water}}$

Specific gravity = $\frac{\text{density of gold}}{62.4 (lbs.ft^{-3})}$

Now, calculate the density of gold then from density we will calculate specific gravity as follows

Since, Density = $\frac{mass}{volume}$

Density = $\frac{645 lbs}{0.5348 ft^{3}}$

= 1206.06 $lbs/ft^{3}$

As, Specific gravity = $\frac{\text{density of gold}}{\text{density of water (standard fluid)}}$

= $\frac{1206.06 (lbs/ft^{3})}{62.4 (lbs/ft^{3})}$

= 19.32

Therefore, the value of specific gravity is 19.32.

Specific gravity has no units as it is density divided by density. Hence, all the units get canceled out.

What is the difference between an introduced species and an invasive species?

a_sh-v [17]

Answer and Explanation:

The introduced species is, literally, a species that was introduced into an environment by human action. In other words, an introduced species is one that is not native to a region, does not occur naturally, but has been taken by humans to that region.

An invasive species, on the other hand, is one that was introduced naturally in an environment, but multiplied in a harmful way, causing a strong imbalance in the region.

How much heat is needed to melt 100.0 grams of ice that is already at 0°C?

Jet001 [13]

Taking into account the definition of calorimetry and latent heat, the heat needed to melt 100.0 grams of ice that is already at 0°C is 33,400 J (option A).

<h3>Calorimetry</h3>

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

<h3>Latent heat</h3>

Latent heat is defined as the energy required by a quantity of substance to change state.

When this change consists of changing from a solid to a liquid phase, it is called heat of fusion and when the change occurs from a liquid to a gaseous state, it is called heat of vaporization.

In this case, the heat Q that is necessary to provide for a mass m of a certain substance to change phase is equal to

Q = m×L

where L is called the latent heat of the substance and depends on the type of phase change.

<h3>Heat needed to melt ice</h3>

In this case, you have to melt the ice into liquid water.Being the specific heat of melting of ice is 334 J/g, the heat needed to melt 100 grams of ice is calculated as:

Q= 100 grams× 334 J/g

Solving:

In summary, the heat needed to melt 100.0 grams of ice that is already at 0°C is 33,400 J (option A).
