How many fifths are in a half gallon?

The fifth unit of measurement is roughly equal to 25.6 fluid ounces or 750 milliliters; milliliters are the more common modern method of measuring alcohol as of 2014, including wine in standard-size bottles. Wine and distilled liquor were bottled in fifths until 1973, which is the year the metric system began replacing the English measurement system in the United States. Beer continues to be sold in bottles marked with the total number of ounces, generally ranging from 12 to 40.

What is the specific heat of brass?

Specific heat is the amount of heat needed to raise the temperature of one unit of mass by one degree Celsius. The formula mass times the change in temperature divided by the heat added gives the value of the specific heat of a material as long as no phase changes (e.g. going from a liquid to a gas) occur. Copper has a similar specific heat to brass, so they both require about the same amount of energy to raise by one degree Celsius. Gold has a specific heat of 0.129 which is very low.

What is the chemical name for Nh3?

Ammonia dissolves in water, is corrosive and contains alkaline properties. Ammonia is primarily transported as a compressed liquid in steel containers and is not very flammable but may ignite if exposed to high temperatures. Exposure to small amounts of ammonia in the air can cause irritation to the skin, eyes and lungs, while being exposed to higher amounts and for longer periods of time, ammonia can cause pulmonary congestion, excessive coughing, difficulty with breathing and even death.

How do you make your ears pop?

Pinch your nose closedPinch your nose closed so that air cannot travel through it. Take a deep breathTake a deep breath, and hold it for a few seconds. Blow through the noseAttempt to breathe hard through your nose. The sudden change in pressure should help open the eustachian tubes in the ears and unclog them. Repeat the processIf one or both ears are still clogged, repeat the process until the ears open.

What is electric field intensity?

An electric charge builds an electric field and is known as the "source charge." The intensity of this electric field can undergo measurement by any other charge that exists in the general area. A test charge measures the electric field intensity, and it has a charge expressed by the letter "q." When the test charge is set inside the electric field, a force acts on that charge, either repulsive or attractive, and this force is expressed by the letter "F." Defining the magnitude of this field requires knowing the force per charge in place. So electric field intensity equals force divided by tes..

What hormones are secreted by the kidneys?

The kidneys also help a person maintain steady levels of calcium and phosphorus through the conversion of inactive Vitamin D into an active form of Vitamin D. The Merck Manual reports that this inactive form, called calcitriol, performs a similar function as a hormone. It allows the body to absorb calcium and phosphorus from the small intestine

What are examples of convergent evolution?

While sharks and dolphins have no close family relationship in the evolutionary tree, they live in similar environments. Natural selection causes each of these species to evolve similarly. They need fins for swimming and a long sleek body to move through the water, yet sharks receive their oxygen through gills while dolphins must surface to breathe.\nSugar gliders are native to Australia, while flying squirrels are from the United States. Both animals have similar rodent bodies and skin attached between their body and forearm, allowing them to glide from trees. These two animals live in simila..

How do you describe the process of nucleic acid hybridization?

Nucleic acid hybridization can be used to create a hybrid strand of DNA and RNA. When two different molecules have bases that are complementary and can be associated with one another, the process of nucleic acid hybridization can bring them together into a unified strand. This is usually done by exposing the strands and molecules to heat, which denatures them. The National Center for Biotechnology Information goes on to explain that once this has been done, the old pairings are no longer held together, and a hybrid strand can be arranged.\nNucleic acid hybridization can be used to combine stra..

What is C-reactive protein?

Conditions that potentially result in elevated C-reactive protein levels are arthritis, lupus and other autoimmune diseases. Sometimes patients with these conditions don't have an elevated level, however. Elevated results are also associated with the risk of cardiovascular diseases such as heart attack and stroke. The doctor ordering the test can evaluate the results with regard to the particular patient and treat that individual accordingly.

What are some examples of porous materials?

Volcanic rocks, including pumice, tend to be porous. These rocks tend to be a good example of the fact that a porous material doesn't necessarily have holes that cut through the entire material. Some porous materials have little interconnections between pores. For example, volcanic rocks tend to be made up of hundreds of tiny pores that are only a few centimeters deep. In this sense, porous materials are rarely sieve-like. For instance, bone is a porous material, but it is also solid and strong enough to bear weight and stand up to a relatively high level of shock. Similarly, wood is cons..
