How do convention currents move?
Heated from the bottom, the warmer substance will slowly rise to the top while the cooler substance at the top falls to the bottom to be heated again. Look at a lava lamp. That is all about convection currents.
What type of substance is heated by radiation?
Any substance that absorbs the radiation is heated by it.
What would increase a temperature of a substance?
When a substance is heated the temperature is increased. This occurs because energy enters the substance which will increase the kinetic energy of the molecules,thus causing a rise in temperature.
What happens if a substance of unknown composition is heated in a sealed container As a result the mass of the container and its contents?
If a substance of unknown composition is heated in an open container will Its mass will stay the same as a result the mass of the container and its contents decreases. A substance of an unknown composition is heated in a sealed container the mass of the container and its content remains the same.
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.

Do molecules rise or sink after they are heated?
Rise
Does heated air rise or sink?
rise
How does the volume and density of a substance change when it is heated?
The volume of a substance increases when heated, causing a decrease in density.
What substance is heated with limestone to prodce cement?
its heated with something

When substance are heated they?
They expand
How does baking soda assist in making our cakes rise?
This is a total guess, but i think its because when the substance(baking soda) is heated aka in the cake in the oven, its atoms vibrate and create air pockets and bubbles. there fore making it rise.
Why does the heat rise in convection?
There is a general tendency for objects to expand when they get hotter - this includes air, and gases in general. As a result, they have less density (mass per unit volume); and objects with less density tend to float or rise.
Does the volume of an object change if heated?
The volume of a substance increases when heated
