Explanation:
You may know that electricity flows through wires. Wires are good conductors of electricity. Heat too can be transferred, or conducted, through some types of materials. The term conduction refers to the transfer of energy. Conduction occurs when energy is passed between objects.
The transfer of thermal energy is called heat. Particles of matter are in constant motion. Sometimes they collide with other particles. When they do, they transfer some of their energy. The energy is transferred from particle to particle. It is sort of like a row of dominoes falling over. In this process, thermal energy moves through a substance. It can even move into other nearby substances conduction occurs between particles of the metal in the pot. It also occurs between particles of the pot and the water. Figure below shows additional examples of conduction. Did you ever cook over a campfire? The man in Figure below is cooking his lunch. He waits as his food absorbs energy. First, the energy from the fire needs to heat the water. Soon, all the water in the pot will be boiling hot. The man also feels warm. He feels the heat from the flames. He feels the warmth even though he is not touching the flames. Thermal energy is transferred from the fire to his hands.
Answer:
Fusion rates and star evolution increase rapidly because of the conversion of hydrogen molecules to helium.
Explanation:
At the early stage of a star mass, hydrogen atoms are produced. After a few billion years, these hydrogen atoms formed at the core of the star mass begin to fuse on the external side of the core. Hydrogen atoms get rapidly fused, resulting to a contraction of the star core, and as more hydrogen atoms get fused, helium atoms are formed.
This action results into rapid into a rapid and violent burning action of hydrogen atoms around the core.
The car's average speed during that time is (23.7/2) = 11.85 m/s .
Distance = (11.85 m/s) x (6.5 sec) = 77.025 meters .
Neutral Magnesium atom
Explanation:
From the given description of the atom, one can infer that this atom is a neutral atom.
In a neutral atom, the number of protons and neutrons are the same.
Atomic number = 12
Mass number = 25
This atom is Magnesium.
Magnesium has an atomic number of 12 from the periodic table.
Number of protons = 12 = atomic number
Number of electrons = 12(for neutral atoms, atomic number is same as number of electrons).
Number of neutrons = mass number - atomic number = 25-12 = 13.
