Answer:

The correct answer is water electrolysis.

Explanation:

Water electrolysis is the decomposition of water (H2O) into the gas oxygen (O2) and hydrogen (H2) using a continuous electric current, supplied by a power source, which can be a battery or a battery, which is connected by electrodes to water. This reaction is endothermic, and the products of the reaction are hydrogen and oxygen in a gaseous state.

Have a nice day!

How does the mass of a bowling ball that has been rolled down the lane affect the kinetic energy?
Simora [160]

Answer is: B) The kinetic energy is increasing proportional to the mass of the bowling ball.

Kinetic energy has to do with the speed of an object and how much mass it has; basically how the object is moving.

Ek = 1/2 · m(bowling ball) · v²(bowling ball).

m is mass; v is speed of bowling ball.

The standard unit of kinetic energy is the joule.

Air trapped in a cylinder fitted with a piston occupies 145 mL at 1.08 atm
pav-90 [236]

Answer: 0.0014 atm

Explanation:

Given that,

Original pressure of air (P1) = 1.08 atm

Original volume of air (T1) = 145mL

[Convert 145mL to liters

If 1000mL = 1l

145mL = 145/1000 = 0.145L]

New volume of air (V2) = 111L

New pressure of air (P2) = ?

Since pressure and volume are given while temperature is held constant, apply the formula for Boyle's law

P1V1 = P2V2

1.08 atm x 0.145L = P2 x 111L

0.1566 atm•L = 111L•P2

Divide both sides by 111L

0.1566 atm•L/111L = 111L•P2/111L

0.0014 atm = P2

Thus, the new pressure of air when the volume is decreased to 111 L is 0.0014 atm
