Hello!
a gas thermometer measure temperature by measuring the pressure of a gas inside the fixed volume container a thermometer reads a pressure of 248 torr at 0 degrees Celsius what is the temperature when the thermometer reads a pressure of 345 torr
We have the following information:
P1 (initial pressure) = 248 torr
T1 (initial temperature) = 0 ºC (in Kelvin)
TK = TºC + 273.15 → TK = 0 + 273.15 → T1 (initial temperature) = 273.15 K
P2 (final pressure) = 345 torr
T2 (final temperature) = ? (in Kelvin)
According to the Law of Charles and Gay-Lussac in the study of gases, we have an isochoric (or isovolumetric) transformation when its volume remains constant or equal, then we will have the following formula:
![\dfrac{P_1}{T_1} = \dfrac{P_2}{T_2}](https://tex.z-dn.net/?f=%5Cdfrac%7BP_1%7D%7BT_1%7D%20%3D%20%5Cdfrac%7BP_2%7D%7BT_2%7D)
![\dfrac{248}{273.15} = \dfrac{345}{T_2}](https://tex.z-dn.net/?f=%5Cdfrac%7B248%7D%7B273.15%7D%20%3D%20%5Cdfrac%7B345%7D%7BT_2%7D)
![248*T_2 = 345*273.15](https://tex.z-dn.net/?f=248%2AT_2%20%3D%20345%2A273.15)
![248\:T_2 = 94236.75](https://tex.z-dn.net/?f=248%5C%3AT_2%20%3D%2094236.75)
![T_2 = \dfrac{94236.75}{248}](https://tex.z-dn.net/?f=T_2%20%3D%20%5Cdfrac%7B94236.75%7D%7B248%7D)
![T_2 = 379.9868952... \to \boxed{\boxed{T_2 \approx 380\:K}}\end{array}}\qquad\checkmark](https://tex.z-dn.net/?f=T_2%20%3D%20379.9868952...%20%5Cto%20%5Cboxed%7B%5Cboxed%7BT_2%20%5Capprox%20380%5C%3AK%7D%7D%5Cend%7Barray%7D%7D%5Cqquad%5Ccheckmark)
If you want the solution in Celsius Temperature, we have:
TC = TK - 273.15
TC = 380 - 273.15
TC = 106.85 → Temperature = 106.85 ºC

Answer:
Magnet with a positive and a negative pole
Explanation:
A great analogy to demonstrate what a polar molecule looks like is to imagine a magnet. A magnet has one positively charged end and one negatively charged end, two poles, that is.
Imagine that we have a magnet of a shape of a prism (water molecule has a bent shape). The two base vertices of the face of the triangle are positively charged, that's because hydrogen is less electronegative than oxygen and, hence, the two hydrogen atoms are partially positively charged in a water molecule.
Oxygen is more electronegative than hydrogen meaning it has a greater electron-withdrawing force, so electrons are closer to oxygen within the O-H bonds. Oxygen, as a result, becomes partially negatively charged, so it's our negative pole of the magnet.
Answer:
The answer will be Ligand A with a dissociation constant (Kd) of
M
Explanation:
When the dissociation constant in the ligand is small (in order of nano) (
) it will be more tied. Due to a dissociation constant measures how much a ligand can be able to be separated from the protein so if the number is small it means that the ligand is highly binded to the protein.
On the other hand, the occupancy percentage of the ligand does not imply binding. Conversely, a High-affinity ligand binding with the proteins implies that a relatively low concentration of a ligand is adequate to occupy the maximum ligand-binding site.
