Answer: The volume of the balloon when it is fully cooled by my refrigerator is 0.3 L
Explanation:
To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
![\frac{V_1}{T_1}=\frac{V_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BV_1%7D%7BT_1%7D%3D%5Cfrac%7BV_2%7D%7BT_2%7D)
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
![V_1=0.5L\\T_1=220^oC=(220+273)K=493K\\V_2=?\\T_2=40^oC=(40+273)K=313K](https://tex.z-dn.net/?f=V_1%3D0.5L%5C%5CT_1%3D220%5EoC%3D%28220%2B273%29K%3D493K%5C%5CV_2%3D%3F%5C%5CT_2%3D40%5EoC%3D%2840%2B273%29K%3D313K)
Putting values in above equation, we get:
![\frac{0.5}{493}=\frac{V_2}{313}\\\\V_2=0.3](https://tex.z-dn.net/?f=%5Cfrac%7B0.5%7D%7B493%7D%3D%5Cfrac%7BV_2%7D%7B313%7D%5C%5C%5C%5CV_2%3D0.3)
Thus the volume of the balloon when it is fully cooled by my refrigerator is 0.3 L
Answer:
Option (B)
Explanation:
Crystals are usually defined as those substances that are comprised of atoms, ions, and molecules, and they are oriented in a very well-developed and ordered microscopic structure. These crystals are interlinked to one another by strong chemical bonds, namely the metallic, covalent, ionic and Vander Waals bond. In nature, these crystals form when any liquid undergoes cooling and solidifies.
The study of crystals is commonly known as crystallography and is directly associated with the minerals.
Thus, the correct answer is option (B).
Answer:
B
Explanation:
Frequency and wavelength are inversely proportional
I Believe it would be 46.005500
hoped this helped let me know if I'm wrong
