Answer:
A
Explanation:
B. That's a solid
C. Liquid is the only thing that can have viscosity
D. Not necessarily the case
Answer:
they have same atomic number as they are the same element & electrons
Answer:
the protons
Explanation:
the number of protons is constant for each sample of the element. If the number of protons differs, then it is a different element.
Answer : The correct option is, (d) inversely proportional to volume and directly proportional to the kelvin temperature
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
![P\propto \frac{1}{V}](https://tex.z-dn.net/?f=P%5Cpropto%20%5Cfrac%7B1%7D%7BV%7D)
Charles' Law : It is defined as the volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
![V\propto T](https://tex.z-dn.net/?f=V%5Cpropto%20T)
Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.
![P\propto T](https://tex.z-dn.net/?f=P%5Cpropto%20T)
Combined gas law : It is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
![\frac{PV}{T}=K](https://tex.z-dn.net/?f=%5Cfrac%7BPV%7D%7BT%7D%3DK)
or,
![\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BP_1V_1%7D%7BT_1%7D%3D%5Cfrac%7BP_2V_2%7D%7BT_2%7D)
From the above information we conclude that the pressure exerted by a gas is inversely proportional to volume and directly proportional to the kelvin temperature.
Hence, the correct option is, (d)
