Alpha decay represents the forceful ejection of two protons and two neutrons from the nucleus of the parent atom. If 214 Po undergoes alpha decay, the equation would be:
214 Po ➡️ 210 Pb + 4 He + energy
Alpha decay is in the form of a helium nucleus, two protons and two neutrons.
Answer:
How are density, mass and volume related to each other? How do ... This diagram compares the particles in a gas, a liquid and a solid. ... The following diagram represents one of the glasses pictured above, containing a colourless liquid ... For matter to change from one state to another, its particles must gain or lose energy.
Explanation:
Diffusion occurs faster in a gas than in liquids because in a liquid the molecules are closser together and in a gas they are farther appart
Answer:
A. Erosion
Explanation:
Erosion is the process in which soil and rock are worn away and transported by wind or water and transported to another location.
The image below shows how water has eroded a coastline.
B is wrong. Chemical weathering is the disintegration of rocks by reactions with water and the acids dissolved in it
C is wrong. Deposition is the process in which sediments carried by wind, water or ice are deposited at another location.
D is wrong. Physical weathering is the breakdown of rocks and soil by physical processes like the freezing of ice in the cracks of rocks.
