Answer:
Homeostasis is the quality of a living being to control its inside conditions. A model is the body directing its inside temperature by shuddering or perspiring. The body controls the measures of acids and bases in the blood.

Explanation:
Ionization energy is defined as the energy required to remove the most loosely bound electron from a neutral gaseous atom.
When we move across a period from left to right then there occurs a decrease in atomic size of the atoms. Therefore, ionization energy increases along a period.
But when we move from top to bottom in a group then there occurs an increase in size of the atoms. Hence, ionization energy decreases along a group.
(a) As Sb, Sn and I are all period 5 elements. Hence, these elements are arranged in order of increasing as follows.
Sn < Sb < I
(b) As Sr, Ca, and Ba are all elements of group 2a. Hence, these elements are arranged in order of increasing as follows.
Ba < Sr < Ca
Answer:
chemical change, or chemical reaction.
Explanation:
A change in matter that produces one or more new substances is a chemical change, or chemical reaction. In a chemical change, atoms rearrange to form new substances, which results in different physical properties, as well. ( you could have looked it up on google lol )
Answer: C is the correct answer
Answer:
Volume occupied by gas molecules themselves is not comparable to the volume between molecules.
Explanation:
<em>Which of the following statements describes ideal gas according to the kinetic-molecular theory of gases? </em>
<em>Gas molecules lose energy when colliding into the wall of a container. </em>FALSE. Collisions of ideal gas molecules are considered to be perfectly elastic, that is, no kinetic energy is lost.
<em>Gas molecules attract each other through weak intermolecular forces. </em>FALSE. In ideal gases, intermolecular attractions are negligible.
<em>Volume occupied by gas molecules themselves is not comparable to the volume between molecules.</em> TRUE.
<em>Average kinetic energy of gas molecules is proportional to Celsius temperature.</em> FALSE. Average kinetic energy is proportional to the absolute temperature (Kelvin).
