Which substance is most resistance to weathering?
give example of a real life situation where a substance's resisrance to weathering might make a difference
What is considered a chemical properties of a substance?
Examples: - flammability - resistance to corrosion - resistance to thermal degradation - oxidation - reduction - apptitude for polymerization - chemilumiscence etc.
What do you call the substance that settles out of a suspension?
Sediment
How do you accurately measure the temperature of a substance?
We ca use thermometers, thermocouples, resistance thermometers, pyrometers etc.
What do you call a substance that draws moisture from the air?
hygroscopic
Why liquid is fluid?
A fluid is a substance, such as a liquid or gas, that can flow, has no fixed shape, and offers little resistance to an external stress.
What is the ability of substance to slow down the electricity?
The property of a substance enabling it to slow down electricity is called resistance and is measured in ohms. This ability is called electrical resistance. Every substance has this. Gold has the minimum resistance for electricity. Such substance is called electrical conductor. And there are substance where the electrical resistance is affected by heat, light and other conditions. And for those substance where electricity can not flow are called electrical insulators (non-conductors) such as wood and ceramics.
What is the difference between a fluid and a paste?
A paste is a semi solid mixture which may flow slowly...a fluid is a substance that can flow, has no fixed shape and offers little resistance to external stress.
What is a substance that has no internal resistance to flow?
its a liquid
What air and water resistance?
Air resistance is that resistance when substance moves in air and it expresses a opposite force on it. However, water restinace is water when a substance moves thorugh water and it expresses and oppoisite force.
CAN WATER DECREASE A SUBSTANCE'S RESISTANCE TO FLOW OF ELECTRICITY?
no
Which Property of material offers resistance to scratching is?
Hardness
What increases the?
The thermal vibration of the atoms in the material increases the resistance of that substance. The resistance is greatly depends on temperature.
Which substance is most resistance to weathering rock or sand?
Sand
What type of resistance - high or low - do conductors and insulators have?
A component of a given size that offers low resistance is called a good conductor.A conductor having some appreciable resistance is called a resistor.A component of identical size that offers a higherresistance is called a poor conductor.An insulator of the same size offers even higherresistance.
What is a substance call that does not dissolve in a liquid?
its an insoluble substance
Why do each substance have different amount of resistance?
Resistance of a material is depend on the force required to withdraw electrons from the atoms of that material.
