Answer:
He is most well known for discovering the role Oxygen plays in combustion
Explanation:
<u>Answer:</u>
<em>The amount of energy needed when water at 72 degrees c freezes completely at 0 degrees c is 
Joules</em>
<em></em>
<u>Explanation:</u>
where
= Final T - Initial T
=30125J
Q is the heat energy in Joules
c is the specific heat capacity (for water 1.0 cal/(g℃)) or 4.184 J/(g℃)
m is the mass of water
mass of water is assumed as 100 g (since not mentioned)
is the heat energy required for the phase change
=mass × heat of fusion
Total heat = 
Total Heat = 30123J + 33600J
= 63725 J
= Joules is the answer
Answer:
Its separates the components of heterogeneous mixtures.
like examples :-
- liquids in liquids,
- solids in liquids,
- solids and liquids in gases.
Kinetic energy is the energy from movement. Hence the fastest movement is at the bottom of the loop - therefore Kinetic energy is highest at the flat bottom of the loop.
Potential energy is the opposite - it occurs at the top of the loop when the car moves the slowest
