The pressure of the gas will become double when its Kelvin temperature becomes its initial value.
Further Explanation:
Ideal gas equation:
Ideal gas is just a theoretical concept and practically no gas can act as ideal. It can be considered as group of random moving particles having perfectly elastic collisions between them.
Ideal gas equation for one mole of gas is mentioned below.
PV = RT …… (1)
Here,
P is the gas pressure.
V is the gas volume.
T is the absolute temperature of gas.
R is the universal gas constant.
Standard conditions refer to state when pressure of gas is 1 atm and its temperature is 273 K.
Consider P’ and T’ to be new pressure and temperature respectively while all other terms in ideal gas equation remains constant. Equation (1) then modifies as follows:
P’V = RT’ …… (2)
Since new pressure is doubled, P’ becomes 2P. Equation (2) becomes,
(2P)V = RT’ …… (3)
Dividing equation (3) by equation (1), we get:
…… (4)
Solving for T’,
Therefore pressure is doubled when temperature becomes twice its initial value.

Answer : Option B) Moving them farther apart.
Explanation : Force (F) is inversely proportional to distance (D) separated by charges.
When Electrostatic force is found to be inversely proportional between two positive charges which is separated by a distance D, then to decrease the electrostatic force of one can try to change the distance between the two positive charges in such a way that it increases the distance and decreased the electric force. The best option would be to move the them far apart from each other.
(2) CH3CHCH2 and CH3CH2CH3
(3) CH3CHO and CH3COCH3
(4) CH3CH2OH and CH3OCH3
Answer is (4) - CH₃CH₂OH and CH₃OCH₃.
Both CH₃CH₂OH and CH₃OCH₃ have same molecular formula as C₂H₆O. But CH₃CH₂OH is an alcohol and CH₃OCH₃ is an ether.
Although two compounds have a same molecular formula, the atomic arrangement of those compounds differs from each other.
Hence, CH₃CH₂OH and CH₃OCH₃ are isomers of the formula C₂H₆O.
Due to the different arrangement of atoms, both compounds have different chemical and physical properties.
0.01325 = 1.325x10^-2 or 13.25 x 10^-3 or 132.5 x 10^ - 4 or 1325 x 10^-5. Scientific notation is the standardized way to represent any number as the product of a real number and a power of ten.
The number 0.01325 is expressed in scientific notation as 1.325 x 10^-2. The number of significant figures remains the same.
The starting value 0.01325 can be converted to scientificnotation by first moving the decimal place. In this case, the decimal moved to the right by 2 places, making the number 1.325. So the number in scientific notation becomes 1.325 x 10^-2. Notice that there are still the same 4 significant figures (1, 3, 2, 5) in the number 1.325 as in the original number 0.01325.

Answer : The correct option is (A) Salt.
Explanation :
Solute : It is defined as a substance which is dissolved in a solvent. It is a smaller component of a solution.
Solvent : It is defined as a substance that dissolves a solute. It is a larger component of a solution.
In a salt and water solution, the solute is salt component and the solvent is water component.
Therefore, the correct answer is Salt.
The solute must be able to react with water at the given temperature.
There must be enough energy to break the chemical bonds in the water molecules.
The temperature must be high enough to cause the solute to melt.
In order for a solute to dissolve in a solvent, the attractive forces between solute particles and the solvent particles must be stronger than the attractive forces between solute-solute and solvent-solvent particles. This is important so that the solute will remain in solution.
