The coefficient of linear expansion (Kl ) for silver is 0.0000189. I = LKl (To - Tf ) I = 1.4 m × 0.0000189 × (55°C - 10°C) I = 1.4 × 0.0000189 × 45 NOW=A silver bar 0.125 meter long is subjected to a temperature change from 200 degrees celsius to 100 degrees celsius what will be the length of the bar after the temperature change? I=LKI (T0-Tf) =>I=0.125×0.0000189×(200-100) =>I=0.00023625
To calculate the linear expansion or contraction of an object it is necessary to use the following equation:ALc/Lo = Î± x TcWhere:Lc = Change in length (m)Lo = Original length (m)Î± = Linear Temperature Expansion Coefficient (10-6 m/K)Tc = Change in temperature (K)The Linear Temperature Expansion Coefficient of SilverA = 18.9x10-6 m/KRearranging the equation to make Lc the subject yields:Lc = Î± x Tc x LoLc = 18.9x10-6 x -100 x 0.125Lc = -0.00023625Change in length of bar = -0.00023625 mNew Length of bar = 0.125 - 0.00023625New Length of bar = 0.12476375 m
L2 = L1 + Delta L = L1 + ( L1) ( CLEXP ) ( Delta T )L2 = 0.125 m + ( 0.125 m ) ( 19.5 x 10^-6 m / m - C ) ( -100 C )L2 = 0.125 m - 0.000244 m = 0.124756 m
For the temperature range of most interest for humans, silver is a solid that doesn't change as much in volume over temperature as Mercury does.
No, the element of silver is not flammable and will not catch fire. However, this element does melt when subjected to extreme temperatures.
The state of silver at room temperature is a solid.
Would you please expand your question to include another reactant, or the conditions to which the silver nitrate would be subjected when you resubmit it.
When the physical properties of a material are changed due to the application of a force. Example: Colloidal silver particles suspended in a photosensitive material precipitate when subjected to light. Example: Radioactive decay.
A solid..... The element silver is a solid at room temperature.
Drawing it into a wire is a physical change of silver.
tarnishing of silver is a chemical change
At room temperature silver is a solid.
Silver boils at 2,210 degrees Celsius
Yes. Silver tarnishing is a chemical change.
Any pure substance, including silver, at melting temperature can be either liquid, solid, or both. That is the defining characteristic of the melting temperature.
The natural state of silver is solid at room temperature.
At standard temperature and pressure, silver is a solid.
The melting point of silver is 1,763°F.
Silver is a solid at room temperature, meaning that it is already frozen. The cutoff point is 961.78 degrees. As long as the temperature is below this, than silver is frozen.
You would need to know if the silver underwent change that left the silver as it was originally, (in this case, having a black substance attach to it) or a change that made the silver into a new substance (like tarnishing). If the silver is still the same before and after the change, it was a physical change. If the substance is changed into a different substance after the change, it is a chemical change.
