Select all that apply. which of the following statements about boyle's law are correct?
1. the temperature and pressure must remain constant for the law to apply.
2.the temperature and the number of molecules must remain constant for the law to apply.
3.as the pressure of a gas increases, the volume increases proportionally.
4.as the pressure of a gas increases, the volume decreases proportionally.

Answer : The correct options are,

2. The temperature and the number of molecules must remain constant for the law to apply.

4. As the pressure of a gas increases, the volume decreases proportionally.

Explanation :

Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

or,

where,

P = pressure of gas

V = volume of gas

k = constant

From this we conclude that, pressure is inversely proportional to the volume of gas that means as the pressure increases, the volume of gas decreases.

Hence, the correct options are, (2) and (4)

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
