<h2>The difference between matter, mass, and volume is that:</h2>
<u>Matter</u> is a physical substance which can be touched, seen, smelled, and sometimes heard. It comes in different states: liquid, solid, gas, and plasma.
<u>Mass</u> is the measure of how much <u>matter</u> is in an object.
<u>Volume</u> is the measure of how much space is inside of a 3D object.
This is the pattern formed in a fluid when heating causes part of the fluid to rise and then cooling causes it to sink again. Within Earth's mantle they circulate heat and drive plate tectonic processes. Within the atmosphere and oceans, they drive winds and weather patterns:Convection Cell
Answer:
3). Chemical potential energy
1). lower in charcoal than in coal.
Explanation:
Chemical potential energy is defined as the energy that can be absorbed or stored in a substance's chemical bonds. It can be released when there is a change in the number of particles of the substance.
As per the question, coal releases more heat than charcoal because 'the chemical potential energy of charcoal is lower than the coal' <u><em>and hence, the latter would release more heat on burning i.e. the energy that was absorbed in the chemical bonds of the substance</em></u>. Hence, option 3 and 1 are the correct answers.
In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change.

Answer:
5.95g
Explanation:
1
= 1000 mL
∴ 100 mL = 100 ÷ 1000 = 0.1 
Volume = <u>0.1 </u>
<u />
Concentration = <u>0.5 M</u>
Concentration =
0.5 = 
No. of moles = 0.5 x 0.1 = <u>0.05 moles</u>
No. of moles =
Mass in 1 mole of KBr = 39 + 80 = 119g (39 is the mass of potassium and 80 is the mass of bromine)
0.05 = 
x = 119 × 0.05 = 5.95g
