11. The density of liquid chloroform is 1.48 g/mL. What is its density in units of lb/in?(2.54 cm = 1 in., 2.205 lb = 1 kg)

Answers

The density of the liquid chloroform is 0.0535 lb/in³.

The given parameters:

  • Density of the liquid, = 1.48 g/mL

The density of the liquid chloroform in pounds per cubic inches (lb/in³) is calculated by multiplying with the appropriate equivalent units as demonstrated below;

\rho = 1.48 \ (g)/(mL) * (1 \ mL)/(cm^3) * ((2.54cm)^3)/((1\ in)^3) * (1 \ kg)/(1000 \ g) * (2 .205 \ lb)/(1 \ kg) = 0.0535 \ lb/in^3

Thus, the density of the liquid chloroform in pounds per cubic inches is determined to be 0.0535 lb/in³.

Answer:

5.35*10^-2\ lb/in^3

Explanation:

Given density of chloroform is 1.48 g/mL

We need to find the density in lb/in^3

Also, we have given 2.54 cm = 1 in and 2.205 lb = 1 kg

We know 1ml=1cm^3

Also, 2.54 cm = 1 in

2.54^3\ cm^3=1\ in^3\n16.38\ cm^3=1\ in^3\n16.38\ cm^3=16.38\ ml=1\ in^3

And 1000 g = 1 kg

1\ g=(1kg)/(1000)\n\n1\ kg=2.205\ lb\n\n1\ g=(2.205\ lb)/(1000)=2.205*10^(-3)\ lb

Now we will plug

1\ ml=(1)/(16.38)\ in^3 \n\nAnd\ 1\ g=2.205*10^-3\ lb

So,

1.48\ (g)/(ml)=1.48* 2.205*10^(-3)(lb)/((in^3)/(16.38) )\n \n=1.48*2.205*16.38*10^(-3)(lb)/(in^3)\n =5.35*10^(-2)(lb)/(in^3)

What is one biotic factor that limits the carrying capacity of any habitat

Answers

Biotic components are the living components of an ecosystem. The biotic factor that limits the carrying capacity of any habitat is activity of decomposers, i.e., option B.

What are decomposers?

The organisms that usually feed on dead and decaying organisms and whose digestion is external one are called as decomposers.

The bioticfactor that limits the carryingcapacity of any habitat is activity of decomposers.

Thus, the correct option is B.

During an experiment a student measured the temperature of water while it boiled in a pot on a stove. The temperature of the water stayed at 100°C during the entire time that the water was boiling.

Answers

Answer:

The temperature of the water stayed at 100^(0) C because the temperature of a pure water does not increase at its boiling point, 100^(0) C. This is due to latent heat of vaporisation.

Explanation:

During a change of state of a substance, the temperature does not change due to latent heat of the substance. Latent heat is the amount of heat required to convert a unit mass of a substance from one state to another without a change in its temperature. There are two types of latent heat, latent heat of fusion anf latent heat of vaporisation.

So during the experiment, the water got to its boiling point and continues to boil at this constant temperature until it would change completely to steam at that temperature. After the conversion process, the temperature begins to increase.

The latent heat of vaporisation came into action during the process of boiling the water at constant temperature. That's why the temperature of the water did not increase even after reaching its boiling point (100^(0) C ).

Answer:

c,interpretation of the data

Explanation:

A good scientific explanation needs to be based on both data collected in an investigation and on the ability to interpret what the data means.

Normally, adding heat energy increases the temperature of a substance. However, during a phase change, the temperature of the substance stays constant. This happens because the heat energy is being used to change the phase of the matter instead of the temperature.
