At constant temperature and volume the pressure of a gas is directly proportional to the number of moles of the gas. PV =n RT, where R is the universal gas constant. A change in pressure depends with the number of moles of the gas, such that if the number of moles increases then there are many vibrations and collision of the gas molecules with the walls of a container thus increasing the pressure and vice versa.
Chlorine needs to gain one electron and sodium needs to lose one electron
The changing force is you swinging the STRING

this is similar because it’s on a set path and you are the earth and the gravitational pull is from the earth which the string represents
they need the Sun's energy in order to produce food

There are several starting ingredients that are required for starting the process of photosynthesis. The most important are sunlight, water, carbon dioxide and certain minerals. Sunlight helps in building up the optimum temperature that is required to start the process of photosynthesis. Water is an important raw material that helps to absorb the carbon dioxide from the air. It also directly influences the opening and closing of the stomata. Carbon dioxide on the other hand is one of the most important raw material that helps to make glucose via the process of photosynthesis.</span>
