Answer:
A food chain shows how energy is transferred from one living organism to another via food. ... When these animals eat these plant products, food energy and organic compounds are transferred from the plants to the animals.
Answer:
B
101L
Explanation:
We use the ideal gas relation
PV = nRT
P = pressure = 101.3KPa
V = volume = ?
n = number of moles = 4.5moles
T = Temperature = 273.15K
R = molar gas constant = 8.314J/mol.k
Rearranging the equation to make V the subject of the formula yields :
V = nRT/P
= ( 4.5 × 8.314 × 273.15) ÷ 101.3
= 10,219.361 ÷ 101.3 = 100.88L which is apprx 101L

Complete Question:
A soccer player pumps air into a soccer ball until no more air can be pushed inside.Use the particle model to predict what will happen if a sharp object creates a hole in the soccer ball.
Answer:
particles will rush out of the ball until the pressure is equal inside and outside the ball
Explanation:
We need to understand when a ball is pumped with air until no more air can be pushed inside, that the particles inside the ball are closer together and bounce into each other more than the particles outside the ball and this makes the pressure inside the ball greater than that outside.
Now when a sharp object creates a hole in the soccer ball the particle move from a place of high pressure to a place of lower pressure because the force at the place of high pressure overpowers the force at the place of lower pressure.
