Which term is defined as a measure of the average kinetic energy of the particles in a sample?(1) temperature (3) thermal energy
(2) pressure (4) chemical energy

Answers

Answer 1

Answer:

Answer: The correct answer is Option (1).

Explanation:

Average kinetic energy is defined as the average of the kinetic energies that is associated to the particles of the sample which are in random motion.

Temperature is the measure of the average kinetic energy of the particles. Formula used for calculating the average kinetic energy is given by:

$K=(3)/(2)(R)/(N_A)* T$

where,

K = kinetic energy

R = Gas constant

$N_A$ = Avogadro's constant

T = temperature

Kinetic energy is directly proportional to the temperature of the particle.

$\text{Kinetic energy}\propto \text{Temperature}$

As the temperature increases, the kinetic energy of the particles also increases and vice-versa.

Hence, the correct answer is option 1.

Answer 2

Answer: The answer is (1). Temperature is directly proportional to the average kinetic energy of the particles in any given sample of matter, and it is usually defined along those lines.

Which element is a liquid at 758 K and standard pressure?(1) gold (3) platinum
(2) silver (4) thallium

Answers

The answer would be Thallium. This is an element with Tl as its chemical symbol and atomic number 81. This soft gray post-transition steel is not originate free in nature. When inaccessible, thallium look like tin, but tarnishes when unprotected to air.

Answer: option (4) thallium.

Explanation:

1) You have to look at the normal boling and mleting points of the elements.

2) To be liquid the normal melting point must be lower than 758 K and the normal boiling point must be greater than 758 K.

3) The look at the data in a handbook of properties or in internet, and build a table.

4) The given temperature, 758K, is 758 - 273.15 = 484.85 °C.

Element Normal melting Normal boiling State at 484.85 °C

point (°C) point (°C)

(1) gold 1064 2700 solid

(2) silver 961.8 2162 solid

(3) platinum 1768 3825 solid

(4) thallium 303.5 1457.8 liquid

Then, the only element of the choices whose melting point is less than 758 K (484.85) and its boiling point is greater than that, at 1 atm is thallium. So, it is liquid.

Water vapor changing to liquid water

Answers

Explanation:

When water vapour changes to liquid water then this process is known as condensation.

For example, when lid is placed in a hot water filled pan then after sometime vapours appear on the surface of lid. When temperature of water decreases then water vapours convert into liquid form.

Thus, we can conclude that in condensation water vapor changes to liquid water.

The temperature at which a substance boils is an example of a physical property.a. True
b. False

Answers

A physicalproperty is any property that does not concern with the change of the substance.The changes in the physical property can be used to describe itstransformations or evolutions from its initial state. They are often referredto as observables. Temperature at which asubstance boils is an example of a physical property. The temperature at which a substance boils describes astate of a physical system. It describes the transformation of a liquid fromits liquid state to its vapor by increasing its temperature.

The answer would be (a.)True.

What is a common use of nitric acid?

Answers

We can see here that some common uses of nitric acid:

Manufacturing of Fertilizers: Nitric acid is a key component in the production of nitrogen-based fertilizers, such as ammonium nitrate and urea.

Production of Explosives: Nitric acid is used in the manufacturing of explosives, including dynamite, trinitrotoluene (TNT), and nitroglycerin.

What is nitric acid?

Nitric acid is a highly corrosive and strong mineral acid. It is a clear or yellowish liquid that is commonly used in various industrial, laboratory, and chemical applications.

In its pure form, nitric acid is a colorless liquid, but it can have a yellowish tint due to the presence of nitrogen dioxide, which forms when nitric acid reacts with air.

A chemical reaction has two elements as reactants. Which type of reaction might occur?

Answers

Chemical changes are a result of chemical reactions. All chemical reactions involve a change in substances and a change in energy. Neither matter or energy is created or destroyed in a chemical reaction---only changed. There are so many chemical reactions that it is helpful to classify them into 4 general types which include the following:SYNTHESIS REACTION
In a synthesis reaction two or more simple substances combine to form a more complex substance. Two or more reactants yielding one product is another way to identify a synthesis reaction.
For example, simple hydrogen gas combined with simple oxygen gas can produce a more complex substance-----water!
The chemical equation for this synthesis reaction looks like:

reactant + reactant -------> product
To visualize a synthesis reaction look at the following cartoo
In the cartoon, the skinny bird (reactant) and the worm (reactant) combine to make one product, a fat bird.
DECOMPOSITION REACTION
In a decomposition reaction a more complex substance breaks down into its more simple parts. One reactant yields 2 or more products. Basically, synthesis and decomposition reactions are opposites.
For example, water can be broken down into hydrogen gas and oxygen gas. The chemical equation for this decomposition reaction looks like:

reactant -------> product + product
To visualize a decomposition reaction look at the following cartoon:In this cartoon the egg (the reactant), which contained the turtle at one time, now has opened and the turtle (product) and egg shell (product) are now two separate substances.SINGLE REPLACEMENT REACTION
In a single replacement reaction a single uncombined element replaces another in a compound. Two reactants yield two products. For example when zinc combines with hydrochloric acid, the zinc replaces hydrogen. The chemical equation for this single replacement reaction looks like:

reactant + reactant ---------> product + product
To visualize a single replacement reaction look at the following cartoon:

Notice, the guy in the orange shirt steals the date of the other guy. So, a part of one of the reactants trades places and is in a different place among the products.DOUBLE REPLACEMENT REACTION
In a double replacement reaction parts of two compounds switch places to form two new compounds. Two reactants yield two products. For example when silver nitrate combines with sodium chloride, two new compounds--silver chloride and sodium nitrate are formed because the sodium and silver switched places. The chemical equation for this double replacement reaction looks like:

reactant + reactant ---------> product + product
To visualize a double replacement reaction look at the following cartoon:
