Answer:
Characteristics that can be observed or measured without changing the chemical nature of the substance. but if you go to quizzlet it could help you too it has flash cards that could help
Explanation:
Answer:
The answer is C (same age as Q)
Explanation:
<span>Since you did not show any
picture, I will be describing Dalton’s atomic theory. The scientist thought
that the atom was the smallest particle in the universe is John Dalton. He
established five theories relating atoms. One, elements are made of extremely
small particles called atoms. Two, atoms of different element have different
sizes, mass and physico – chemical properties. Three, atoms cannot be divided
further, destroyed or created. It also follows the law of conservation of
energy. Fourth, atoms can combine to form compounds. And lastly, in chemical
reaction, atoms can be combined, separated or rearranged. </span>
One of the Gas Laws that applies to all gases is that P·V = K·T, where P is the pressure, V the volume, T the temperature, and K a constant value.
So, if pressure is doubled and the volume keeps the same, temperature will be doubled as well, thus, the right answer is E.
Answer : The root mean square speed is, 
Explanation :
The formula used for root mean square speed is:

where,
= root mean square speed
k = Boltzmann’s constant = 
T = temperature = 100 nK = 
M = atomic mass of cesium = 132.91 g/mole = 0.13291 kg/mole
= Avogadro’s number = 
Now put all the given values in the above root mean square speed formula, we get:


Thus, the root mean square speed is,
