What is the effect on the volume of a substance when thermal energy is added?
Adding heat to something generally increases its volume. In rare cases, adding heat to something like ice may actually decrease its volume. The increase in volume of a heated gas is much more significant than the increase in volume when solids and liquids are heated.
What happens to particles in a substance when its heated or cooled?
In a solid, the particles start to vibrate a lot.In a liquid, the particles begin to move around faster and faster.In a gas, the particles move extremely fast through the air.
Is it true molten material in the asthenosphere rises in convection currents because heated materials become more dense?
Actually, hot, less dense material rises, and cold, denser material sinks. Denser material will be heavier (per unit volume) and gravity therefore pulls it down. Less dense material has buoyancy and rises. It's very logical.
How is a house heated?
It is heated by the the fire
What substance does not expand on heating?
For example pure silicon doesn't expand in a given range of temperature. Also a mixture of amorphous and crystalline quartz has a thermal expansion coefficient near zero ("Zerodur" from Schott). But the majority of materials suffer thermal expansion.
Which substance gives sulphur dioxide when heated in air?
Burning sulfur-containing materials, such as coal, oil, or natural gas, releases sulfur dioxide when heated in air.
What type of substance is heated by radiation?
Any substance that absorbs the radiation is heated by it.
Which materials is used to make bricks?
Clay or mud like substance. Then it is heated and cooled to form a brick
A graph that shows the change in the temperature of a substance as it is heated will show?
A graph showing the change in temperature of a substance as it is heated will typically show an initial increase in temperature as heat is added, followed by a plateau where the substance changes phase (e.g., from solid to liquid), and then another increase in temperature. The specific shape of the graph will depend on the properties of the substance being heated.
What happens to materials when they are heated?
Most materials expand when they are heated. If they are heated enough, they may change from solid to liquid, or from liquid to gaseous forms.
What substance is heated with limestone to prodce cement?
its heated with something
When substance are heated they?
They expand
Does the volume of an object change if heated?
The volume of a substance increases when heated
What materials shrink when heated?
Materials that shrink when heated include certain types of plastics, rubber, and fabrics.
When a substance is heated the particles do what?
accelerate
What is the name of the substance created when zinc is heated with sulphur?
The substance created when zinc is heated with sulphur is zinc sulfide.
When a substance is blank it gains thermal energy?
When a substance is heated, it gains thermal energy. This increased energy causes the substance's particles to move faster and its temperature to rise.
