Answer:
Semiconductors are poor conductors at low temperatures, but their resistance decreases with increasing temperature.
Explanation:
A semiconductor can be defined as a crystalline solid substance that has its conductivity lying between that of a metal and an insulator, due to the effects of temperature or an addition of an impurity. Semiconductors are classified into two main categories;
1. Extrinsic semiconductor.
2. Intrinsic semiconductor.
The statement which best describes the electrical conductivity of metals and semiconductors is that semiconductors are poor conductors at low temperatures, but their resistance decreases with increasing temperature.
This ultimately implies that, semiconductors are typically an insulator (poor conductor) at low temperatures and a good conductor at high temperatures.
Additionally, conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.
Answer:
The answer to your question is: false
Explanation:
Zinc is a metal, Chlorine is a nonmetal, Zinc can replace another metal not a non metal.
As per the Equation,
Acceleration = Force/Mass
We Can Conclude That,

The scenario whereby the initial pressure is equal to the final pressure is : ( A ) A balloon filled with air is heated from 300k to 600k, causing it to expand and double in size.
<h3>Gay Lussac's law </h3>
Gay Lussac's law states that at constant pressure, the volume of gas is directly proportional to the change in temperature. i.e. V ∝ T. From scenario 1 the change in temperature from 300 K to 600 K shows a 100% increase in temperature which corresponds with the expansion and size doubling of the volume of gas.
Hence we can conclude that The scenario whereby the initial pressure is equal to the final pressure is : ( A ) A balloon filled with air is heated from 300k to 600k, causing it to expand and double in size.
