Removing salt from water would decrease molarity, molality and ossmotic pressure.
Answer:
Chemical potential energy is the energy stored in the chemical bonds of a substance. The various chemicals that make up gasoline contain a large amount of chemical potential energy that is released when the gasoline is burned in a controlled way in the engine of the car. The release of that energy does two things
Explanation:
The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
The statement which best explains why nickel will reach the ground first is: C. The force of air resistance acts more strongly on the sheet of paper than on the nickel.
<h3>What is gravity?</h3>
Gravity can be defined as a force of attraction that controls the movement of objects and the planets such as Earth around the Sun.
<h3>The factors that affect gravity.</h3>
Some of the factors that affect the force of gravitational attraction that is acting on an object or a physical body include the following:
Generally, nickel will reach the ground first before a sheet of paper due to the effect of the force of air resistance because it would act more strongly on the sheet of paper than on the nickel.
