The method is called the displacement method.
You place some water in the graduated cylinder and measure its volume.
Then you add your object and measure the new volume.
The difference between the two volumes is the volume of your object.
The SA node, the cardiac center in the medulla oblongata, and the endocrine system
K is Potassium
Cl is Chlorine
There are 2 elements.
Answer:
A. it is the lowest at low temperatures
Explanation:
It is true with respect to the kinetic energy of a molecule that the it is the lowest at low temperatures.
The kinetic energy of a molecule is the energy due to the motion of the particles within a substance.
- Kinetic energy is directly proportional to the temperature of a substance.
- The higher the temperature, the more the kinetic energy of the molecules within a system.
- At low temperature, kinetic energy is the lowest.
- At the highest temperature, kinetic energy is the highest
So potassium<span> is </span>more<span> reactive </span>than<span> lithium because the outer electron of a </span>potassium<span> atom is </span>further<span> from its nucleus </span>than<span> the outer electron of a lithium atom.</span>
