what is the relationship between temperature and pressure pls
Answer:
When the temperature of a system goes up, the pressure also goes up, and vice versa. The relationship between pressure and temperature of a gas is stated by the Gay-Lussac's law.
Answer:
We find that temperature and pressure are linearly related, and if the temperature is on the kelvin scale, then P and T are directly proportional (again, when volume and moles of gas are held constant); if the temperature on the kelvin scale increases by a certain factor, the gas pressure increases by the same factor.

Bi D. things
Answer:
The two main variables in an experiment are the independent and dependent variable.

what would happen to dietary protein if hcl were not being produced in sufficient quantities?
Dietary protein will not be digested if Hcl were not being produced in sufficient quantities.
In the stomach, there are some glands found on the stomach lining that helps to release hydrochloric acid (HCl). Their major role is to dissolve food and produce an acidic medium.
The acidic media promotes and improves the conversion of pepsinogen to pepsin. Pepsin acts as an enzyme that supports protein digestion.
Protein digestion requires a pH of around 1.8 which can be achieved by the secretion of HCl.
As a result, if HCI is not released in the stomach in sufficient quantities, pepsin will not be activated and it would have a detrimental impact on protein digestion.
Therefore, we can conclude that dietary protein will not be digested if Hcl were not being produced in sufficient quantities.

Read the article by Michael Fumento, writer for the New York Post editorial blog, who does not support global warming.
Back in 2005 I and others reviewed the entire hurricane record, which goes back over a century, and found no increase of any kind. Yes, we sometimes get bad storms—but no frequently now than in the past. The advocates simply ignored that evidence.
Fact is, the earth was cooling and warming long before greenhouse gases could have been a factor. The [global warming supporters] have been proved wrong time and time again.

Calcium (Ca), strontium (Sr), and barium (Ba) are all located in the same column of the periodic table because they have similar atomic structure and similar chemical properties
Periodic tableFrom the question, we are to determine why calcium (Ca), strontium (Sr) and barium (Ba) are all located in the same column of the periodic table
The periodic table is a tabular arrangement of chemical elements that is arranged by increasing atomic number and groups elements according to recurring properties.
Elements with similar atomic structure and similar chemical properties appear in the vertical columns. These columns are called groups.
Hence, calcium (Ca), strontium (Sr), and barium (Ba) are all located in the same column of the periodic table because they have similar atomic structure and similar chemical properties

Describe the journey that a carbon atom inside a fossil fuel will take to become a carbon atom inside a plant
When fossil fuels are burnt, CO2 is released into the air and is taken up by plants during photosynthesis to form glucose and subsequently starch.
Fossil fuels contain a large proportion of carbon atoms. When fossil fuels are burnt, these carbon atoms are released as carbon dioxide and escape to the atmosphere as atmospheric CO2 in air.
Recall that plants take up the CO2 in air during the process of photosynthesis. This CO2 becomes combined with water in the presence of sunlight to form glucose.
This glucose is converted to starch and stored in plant tissues. This is how the carbon atom inside a fossil fuel becomes a carbon atom inside a plant.

An atom has 7 protons, 8 electrons, and 7 neutrons. What is the charge of the
atom and what type of ion is it?
Answer: An atom containing 7 protons, 8 neutrons, and 7 electrons is charge-neutral.
Explanation:
An atom is composed of protons (positively charged), neutrons (no charge) and electrons (negatively charged). The excess or defect of electrons in relation to protons determines the charge of an atom.
The atom described is an anion with -1 charge as it has one extra electron than protons.
What is an atom?An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.
