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:
chemical symbol: Th
atomic number:90
protrons :90
neutrons:142
group#:4
period#: 9
Explanation:
you take the atomic weight (232.038)and subtract the atomic number to get (90) which is your neutrons
Answer:
a)
The distance between planet and the sun is more that is only gravitational force will act between them.
The gravitational force which act between two planet.
b)
When a car going around a friction force act on the car towards the center.
c)
When the rock at the highest position the tension and gravitational force will act.
d)
The wall of the dryer will apply the normal force.
Answer:
If a material has high thermal conductivity, it is a conductor.
If a material has low thermal conductivity, it is an insulator.
