What do substances do when heated because of the molecules?
they expand
Do substances have to contain water in order to be heated in the microwave?
No, substances do not have to contain water to be heated in the microwave. The microwave oven uses electromagnetic waves to agitate the molecules in the substance being heated, causing them to generate heat regardless of their water content.
Which substance shrinks on heating?
Most substances expand when heated, but water is an exception. Water contracts when heated from 0°C to 4°C before expanding as it heats up further.
What are 2 solid substances that don't go through a liquid state when heated and go straight to gas?
Naphthalene and camphor the process is sublimation
Greater amounts of sugar will dissolve in water if water?
is heated. Heating water increases its ability to dissolve substances, including sugar, by breaking down the sugar crystals more effectively.
What expands when its heated?
Most substances expand when heated.
What do Metals and other substances do when heated?
materials usually expand when heated.
What do substances do when heated because of the molecules?
they expand
Why are substances expanded when they are heated?
because the particles
Why substances often expand when they are heated?
because the particles
What expands when it is heated?
When heated, most substances expand due to the increase in kinetic energy of their atoms or molecules. This leads to an increase in the average distance between the particles, causing the substance to expand.
Do substances have to contain water in order to be heated in the microwave?
No, substances do not have to contain water to be heated in the microwave. The microwave oven uses electromagnetic waves to agitate the molecules in the substance being heated, causing them to generate heat regardless of their water content.
What do most substances like the liquid in a thermometer do when they are heated?
expand
What happens when most substances are heated?
All get very hot.
What happens to a solid when is heated?
A substance in the solid phase will typically expand when heated. Most substances when heated sufficiently will melt into a liquid, assuming that they do not combust or sublimate.
Describe what happens to the particles in substances when the substances is heated?
electrons spontaneously "jump" from a lower orbital to a higher one
What other two substances that yield oxygen when heated?
