Answer:
102.807 kPa
Explanation:
There are some assumptions to be made in the answer. The air inside the balloon acts as an ideal gas at a given temperature conditions.
Using the combined ideal gas equation.
P= absolute pressure of air inside the balloon.
V= volume of air inside the balloon (6.23 L= 6.23 * 10⁻³ m³)
n= moles of gas(air). (0.250 mol)
R= Universal gas constant ( 8.314 J / mol·K)
T= Temperature in Kelvin
T= 35 + 273.15 = 308.15 K
So,
P= 102.807 * 10³ Pa
P= 102.807 kPa
Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.
Plasma is the fourth state of matter. Plasma occurs at extreme high temperatures. It is found in stars, lightning, and neon lights. Plasma is the most commonly found matter in the universe, even though its not common on earth.
In crystalline solids, the particles are arranged in a repeating, three dimensional pattern called a crystal. Some forms of crystalline solids are table salt, sugar, sand, and snow. Diamonds are also crystalline solids.
Gas is a matter that does not have a definite shape or volume.The particles in gas are much father apart than those in a liquid or solid. Gas particles move at high speeds in all direction.
Plasma is different because it can only exist in extremely high temperatures. It is not common on Earth, like the other states of matter. It is only common in the universe. Plasma is found in a lot of things in space. Plasma is not bound to one atom, so it is free. Plasma is formed by adding more heat to the molecules of gas. Eventually, the molecules are moving so fast, that they break apart from their atoms, and then they are positively charged ions, or plasma.
Answer: ENERGY: A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers. These levels are used to describe ecosystem structure and dynamics.
MATTER: When one organism eats another, the matter, or carbon, nitrogen, and other essential elements, are transferred from one to the other. These elements move from the producers, to the consumers, and eventually to the decomposers, cycling the matter through the ecosystem.
