Answer:

The volume will goes to decrease.

Explanation:

The given problem will be solved through the Boyle's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

when pressure is going to increase the volume will goes to decrease and vice versa.

Consider the initial volume is 10 L at initial pressure of 15 atm when pressure is increased to 30 atm the volume will be,

Now we will put the values in formula,

P₁V₁ = P₂V₂

15 atm × 10 L = 30  atm × V₂

V₂ = 150 atm. L/ 30 atm

V₂ = 5 L

Explanation:

Given data:

Mass of hydrogen = 10 g

Number of molecules of ammonia = ?

Solution:

Chemical equation:

3H₂ + N₂       →      2NH₃

Number of moles of hydrogen:

Number of moles = mass / molar mass

Number of moles =  10 g /  2 g/mol

Number of moles =  5 mol

now we will compare the moles of hydrogen and ammonia.

                 H₂            :           NH₃

                  3             :            2

                   5            :           2/3×5 = 3.33 mol

Number of molecules of ammonia:

1 mole contain 6.022 ×10²³ molecules

3.33 mol × 6.022 ×10²³ molecules / 1 mol

20.05  ×10²³ molecules

Answer:

D

Explanation:

Most of the fluids have some resistance to their movement due to viscosity. The gases also exhibit viscosity. The molecules that make up olive oil are larger as compared to alcohol. So olive oil has high viscosity. The correct option is D.

The viscosity of a fluid can be defined as the measure of a fluid's resistance to flow. It can also be known as the measure of a fluid's thickness or its resistance to the objects passing through it.

A fluid with high viscosity resists motion because of its strong intermolecular forces which gives high internal friction. The fluids can flow easily if they have very little intermolecular force of attraction. The SI unit of viscosity is poiseiulle (PI).

Here the molecules which make up the olive oil are found to be shorter than those which make up alcohol. So the oilve oil molecules have more resistance to sliding past one another.

Thus the correct option is D.

Hydrogen sometimes is missing an electron and sometimes it has an extra electron.

Helium (He) and hydrogen (H) are unique elements. Hydrogen has the abilities and electrons of two groups, one and seven, and occasionally has more electrons than it does.

Electrons are defined as a subatomic particle with a negative charge that makes up the nucleus of an atom along with protons and neutrons. For scientists, it can be challenging to monitor them because of how quickly they spin. The tiniest particles in an atom, you can put 2000 of them into a proton, they are drawn to the positive charge of the protons.

Because it has no neutrons in its nucleus, hydrogen (particularly hydrogen -1) is unusual. There is only one proton in the nucleus of hydrogen. The only element without neutrons is this one. Although it has a single electron orbiting its nucleus as well, hydrogen typically contributes this electron to form a single, positively charged proton instead.

Thus, Helium (He) and hydrogen (H) are unique elements. Hydrogen has the abilities and electrons of two groups, one and seven, and occasionally has more electrons than it does.

Answer:

When we cook food in the kitchen, that's the region of higher concentration of the smell. By diffusion, the smell spreads to the whole room and thereby whole house, so anyone standing at a distance, can smell it.

Answer:

smell of cooked food spread fast bc when something is heated up, the kinetic energy of the molecules/particles increases and some of them even mix with the air and moves around. the first answer is also correct (i just explained it more detaily)

so, this is the reason :)

Answer:

There are 504,576,000 seconds in 16 years.

Explanation:

To calculate the number of seconds in 16 years, let's first use simpler units since we are going to be working with large numbers.

First, calculate the number of seconds in one day (24 hours). We can do this with the common knowledge that there are 60 seconds in a minute, and 60 minutes in an hour, multiply the seconds and minutes:

[tex]60*60=3600[/tex]

Therefore, there are 3600 seconds in an hour. Since we know that there are 24 hours in a day, we can multiply the seconds by hours:

[tex]3600*24=86400[/tex]

Therefore, there are 86,400 seconds in a day.

Knowing that there are 365 days in a year, we can multiply 86,400 seconds by 365 days to calculate the number of seconds in a year:

[tex]86400*365=31536000[/tex]

Therefore, there are 31,536,000 seconds in a year.

Since the question is asking the number of seconds in 16 years, we can simply multiply 31,536,000 seconds by 16 years:

[tex]31536000*16=504576000[/tex]

Therefore, there are 504,576,000 seconds in 16 years.
