Diamond has always been considered the hardest natural substance in the world. However, wurtzite boron nitride and mineral lonsdaleite have recently been discoverd and are much harder than diamond.
The second sample is 200/10 = 20 times as large. So its mass will be 20 times as great ie 20*20 grams = 400 grams.
the currents would stop as soon as the heated substace has cold completely.
A compound that does not dissolve in a particular solvent. For example, silver chloride is highly insoluble in water, calcium hydroxide is sparingly soluble in water and sodium chloride is insoluble in chloroform.
Acid rain is caused by the many pollutions we put in our atmosphere that combine together and create an acidic substace that can ruin our cars, statues, and harm are health among other things.
pure substace
Pure Substance: Only contains one elment or conpound.
Tie Substance : Tie Substace can be defined as tie which remain unchanged from raw material to end product in a unit process ..
The substance turns into a gas that is clear and cannot be seen..... This is called condensation when a liguids transforms into a gas

Plant cells have chloroplasts, which contain the substance chlorophyll. Chlorophyll is the key substance that allows plants to convert energy from the sun into chemical energy for sustaining the plant.
Diamond.
it is different bc a substace is like a substace and a compound is like a compound
suspention :]
