It is C. An increase of temperature results in an increase in kinetic energy of the molecules of the substance. For example, in a gas the molecules will move about faster.
Answer:
molarity
Explanation:
Molarity is defined as the number of moles of solute in 1 liter of a solution while molality is defined as the mole of solute in 1 kg of solvent.
<em>If a solution prepared at 20 degrees celsius is heated to 88 degrees celsius, the molarity would change because the volume of a solution is temperature-dependent due to expansion or contraction. The molality, however, will not change for as long as the amount of the solvent remains unchanged due to the heating. </em>
Answer: take out your phone, record things in slow motion mode, and watch it after?
or just try imagining it.
or tell everyone to walk slowly for scientific purposes
yeah thats all i have

Answer:
Explanation:
1 : apple sliced : the apple was cut into smaller peices : physical change
2 : smashed apple : the apple became a mush : physical change
3 : paper burned : the paper became ash : chemical change
4 : glow stick snapped : the glow stick started glowing : chemical change
5 : apple being burned : the apple became discoloured and turned coal-like : chemical change
_____
2. it does not alter the chemical make up of the apple
3. because it changes to a new substance entirely, changing the chemical make up of the paper to make it something new
4. smashing the apple, because you mash up the apple with your teeth in your mouth
5. The apple being burned is being chemically broken down to form a new substance, the same way your stomach digests food to break down and use for other reasons.
