What happen when electric current is passed through water'?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
What device produces light by running an electric current through a gas?
Electric discharge
What happens to gas in a balloon when that gas is heated?
The gas will expand as it is heated.
What is a vacuum discharge tube?
A closed vessel having electrodes at either end and containing agas at low pressure. When a sufficient voltage is applied to theelectrodes, an electric current flows through the gas. Dischargetubes can be used to prevent current flow below a certainvoltage; they can also function as lamps by the use of ionizinggas, which glows when current flows through the tube.
What material conducts electric current poorly?
An element that conducts heat and electrcurrent poorly, and can be a solid, liquid, or gas is a(n)nonmetal.
What is a arc?
discharge: electrical conduction through a gas in an applied electric field
Matter expands or contracts to fill the space available?
Liquid Not liquids,gases.
What do you pass through water to get hydrogen gas?
Electric Current
What happen when electric current is passed through water'?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
A colourless gas which glows with bright light when a electric current is passed through?
The gas most likely described is neon. Neon is an inert gas that can emit a bright orange-red glow when electricity is applied to it, creating what is commonly seen in neon signs.
When electric current is pass through water which gas is obtained from cathode?
oxygen and hydrogen gas
What device produces light by running an electric current through a gas?
Electric discharge
How does electric current travel through gas?
Through ions or electrons.
How do you product hydrogen?
pass an electric current through water - H20, and the current will divide the water molecules into hydrogen gas and oxygen gas
What happen when electric current passes through acidified water?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
What happens when electric current is passed through acidified water?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
What happens when an electric current is passed the gas or vapor of an element?
Rainbows appear
