Taking into account the Gay-Lussac's Law, the pressure will increase by a factor less than three.
Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions against the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.
In summary, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.
Mathematically, Gay-Lussac's law indicates that the ratio of pressure to temperature is constant:
[tex]\frac{P}{T} =k[/tex]
Studying two different states, an initial state 1 and a final state 2, it is satisfied:
[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]
In this case, a given mass of gas in a rigid container is heated from 100 ° C to 300 ° C, that is, it is heated from 373 ° K to 573 ° K. This indicates that the temperature is increasing by a factor less than three. Since pressure is directly proportional to temperature, pressure must increase in the same proportion.
Finally, the pressure will increase by a factor less than three.

Earth contains a spinning electric filed. The spinning of earth core creates its magnetic field. Thus, option D is correct.
What is a spinning body?A body which rotates in its own axis is called a spinning body. Earth rotates about its along with revolving around sun. The outer core of earth generates electric current. This is called telluric current.
Flow of this current creates an electric current which is parallels to the surface of earth. The direction of magnetic field lines will be perpendicular to the direction of current. But it comes stronger when parallel to current.
A rotating electric current results in the generation of a magnetic field. Thus spinning of earth core generates a magnetic field and therefore, option D is correct.

How much eat is absorbed when 50.0g of water changes from 25.0 Celsius to 37.0 Celsius?
which statement is a scientific law
Answer:
It is b
Explanation:
If 0.484J of heat is added to 0.1372g of water, how much will the temperature increase?
0.263 °C
0.927 °c
0.843 °C
0.460 °C
Answer:
ΔT = 0.843 °C
Explanation:
Given data:
Heat added = 0.484 J
Mass of water = 0.1372 g
Temperature increase = ΔT = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Specific heat capacity of water is 4.184 j/g.°C
Now we will put the values in formula.
0.484 j = 0.1372 g × 4.184 j/g.°C× ΔT
0.484 j = 0.574j/°C× ΔT
ΔT = 0.484 j / 0.574j/°C
ΔT = 0.843 °C

Methanol, propan-1-ol and ethanol has boiling point of 65 degree celsius, 97 degree celsuis, 87 degree celsuis respectively. A student uses fractional distillation to separate a mixture of these compound. State which liquid will be collected in the second fraction and explain why
Answer:
ethanol
Explanation:
Methanol has a boiling point of 65°C, propan-1-ol has a boiling point of 97°C and ethanol has a boiling point of 87°C
Fractional distillation is used for separating miscible liquids through the use of the different vapor pressure properties of the liquids. As the mixture is heated up, components start to vaporize according to their boiling points. The component with the least boiling point vaporizes first while the component with the highest boiling point vaporizes last.
This means that methanol would vaporize at the first fraction because it has the lowest boiling point followed by ethanol at the second fraction and then propan-1-ol at the last fraction.
Isopentyl acetate is the molecule largely responsible for the aroma and taste of bananas. It is made up of carbon, hydrogen, and oxygen. Combustion of a 3.256-g sample of isopentyl acetate produces 7.706 g CO2 and 3.156 g H2O. Using these results, what is the correct empirical formula for isopentyl acetate?
Answer:
Explanation:
7.706 g of CO₂ will contain 12 x 7.706 / 44 g of C
= 2.1 g of C .
This will be contained in 3.256 g of isopentyl acetate
3.156 g of H₂O will contain 2 x 3.156 / 18 g of H
= .351 g of H
This will be contained in 3.256 g of isopentyl acetate
Rest will be oxygen
amount of oxygen in 3.256 g of isopentyl acetate
= 3.256 - ( 2.1 + .351 )
= .805 g
ratio of C , H , O in isopentyl acetate
= 2.1 g : .351 g : .805 g
2.1 / 12 : .351 / 1 : 0.805 / 16 ratio of moles
= .175 : .351 : .05 ratio of moles
= 3.5 : 7.02: 1
= 7 : 14 : 2

lonic bonds tend to form between two atoms with what characteristics?
Answer:Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable. Ionic compounds are typically neutral. Therefore, ions combine in ways that neutralize their charges.
Explanation:
Ionic bonds tend to form between two atoms with a high electronegativity difference.
Explanation:
An Ionic bond is defined as a chemical bond in which the complete transfer of electrons occurs from one atom to another.The transfer of electrons occurs from less electronegative atom to highly electronegative atomThe high electronegativity difference between the atomsCompounds with ionic bonds categorized as ionic compoundsSo, from this, we can conclude that ionic bonds tend to form between two atoms with a high electronegativity difference.

Would you expect manganese(II) oxide, MnO, to react more readily with HF(aq) or NaOH(aq)?
Answer:
NaOH(aq)
Explanation:
NaOH(aq) is known to precipitate Mn^2+ ions according to the following reaction; Mn^2+(aq)+2OH^−(aq)↽−−⇀Mn(OH)2(s)
Hence, manganese(II) oxide reacts more readily with NaOH(aq) under ordinary conditions precipitating the metal hydroxide solid. This is one of the characteristic reactions of Mn^2+.
