Heat always flows from cooler objects to warmer objects.
B.
Heat always flows from warmer objects to cooler objects.
C.
Heat never travels in a similar pattern.
D.
Heat never transfers from solids to liquids.
B.) Change in concentration of reactant
C.) Temperature
D.) Particle size
The variables which can affect the speed of a chemical reaction are inihibitor, concentration, temperature and particle size.
Speed of any reaction also known as rate of reaction and it gives idea about the duration that at how much time it will complete.
Hence all of the above will changes the speed of the reaction.

find angle ABE.
Answer:
The measure of angle ABE is 27°.
Explanation:
Consider the below figure attached with this question.
Given information: ∠ABE=2n+7 and ∠EBF=4n-13.
From the below figure it is clear that ∠ABE and ∠EBF are congruent.
Isolate variable terms on one side.
Divide both sides by 2.
The value of n is 10.
We need to find the measure of ∠ABE.
Therefore, the measure of angle ABE is 27°.
The measure of angle ABE is 27°.
Since the angles are congruent, therefore, ∠ABE=2n+7 and ∠EBF = 4n-13 will be equated to each other.
This will be;
2n+7 = 4n-13
Collect like terms
4n-2n = 7+13
2n = 20
Divide both sides by 2.
2n/2 = 20/2
n = 10
Therefore, the value of n is 10.
Since angle ABE = 2n + 7
ABE = 2[10] + 7
= 20 + 7 = 27°.
Therefore, the measure of angle ABE is 27°

The average kinetic energy of water molecules is greatest in steam at 100°C.
Water is a polar solvent that has potential energy on its own which can be converted to kinetic energy once the water is in motion.
The kinetic energy is that energy that a moving body possesses.The faster a molecule moves, the more kinetic energy it has, and the higher the measured temperature.
That being said, when the temperature of water is increased, there would be increased molecular motion leading to a higher kinetic energy.
Therefore, the average kinetic energy of water molecules is greatest in steam at 100°C.
