What state is mercury at 25 degrees Celsius?
At 25 degrees Celsius, mercury is in a liquid state. It has a melting point of -38.83 degrees Celsius and a boiling point of 356.73 degrees Celsius, so at room temperature, it remains fluid. This unique property makes mercury useful in thermometers and barometers.
What acoustic property makes all different instrument and voices sound unique?
timbre
What is a good conductor of electicity a. Arsenic b.Bromine c.Phosphorous d.Selenium e.Sulfur?
Among the options provided, selenium is the best conductor of electricity. It is a semiconductor, meaning it can conduct electricity under certain conditions, unlike arsenic, bromine, phosphorus, and sulfur, which are generally poor conductors. Selenium's electrical conductivity makes it useful in various electronic applications, including photodetectors and solar cells.
What characteristic of radio waves makes them useful for determining the shape of the galaxies?
Radio waves can penetrate interstellar gas and dust without being scattered or absorbed
Is iron a eletrical conductor?

What property makes a metal useful for eletronic devices?
I have absoulutly no idea! I want to know, though!
What are some insolatores?
Some examples of insulators are rubber, glass, plastic, and wood. These materials have high electrical resistance, meaning they do not allow the flow of electricity easily. This property makes them useful for insulating wires, cables, and electrical devices to prevent electric shocks and short circuits.
Why is copper useful for mobile phones?
Copper is used in mobile phones. It is used in all electronic devices and it makes up the wiring in these devices
Is polythene an insulator or a conductor?
Polythene is considered an insulator. It has low electrical conductivity, meaning it does not allow electric current to flow easily through it. This property makes it useful for electrical insulation purposes.
Are polymers good insulators?
Yes, polymers can be good insulators because they have high electrical resistivity compared to metals. This property makes them useful in applications where electrical conductivity needs to be minimized, such as in the insulation of electrical wires or in electronic components.
What makes piezoelectric a smart material?
Piezoelectric materials can convert mechanical energy into electrical energy and vice versa, making them useful in sensors, actuators, and energy harvesting devices. Their responsiveness to mechanical stress or vibrations allows for applications in various fields, from medical devices to structural health monitoring. This unique property makes piezoelectric materials a smart choice for applications requiring sensing or actuation capabilities.
Which metal acts as an insulator?
Metals are conductors, not insulators. Both electrical and thermal conductors.
What property makes semimetals useful as switches to turn a small elecric current on the off?
The property that makes semi-metals useful as "switches" is that their varying ability to conduct electricity.
What property makes certain metalloids useful as switches to turn small electric current on and off?
Metalloids like silicon and germanium have semiconducting properties, which allow them to change their conductivity with small variations in temperature or applied voltage. This property makes them useful as switches in electronic devices to control the flow of small electric currents by turning them on and off.
What property makes steel useful for construction?
because its hard
